ABSTRACT

To study the material basis of cold and hot properties of traditional Chinese medicines (TCMs) in Lamiaceae and to establish a cold and hot properties identification model, a database of material components of TCMs in Lamiaceae was established. A three-level classification system of material components was used to obtain the material basis of cold and hot properties of the Lamiaceae family by using data mining methods such as frequency analysis, association rule analysis, logistic regression, and feature selection. Several identification models were established to recognize the cold and hot properties. The chi-square test results showed that the material composition ratios of cold and hot properties were significantly different at the first-level, second-level, and third-level classification (P < 0.05), and the differences varied as the levels of substance classification changed. The average coefficients of variation were 42.30%, 79.07%, and 91.51% at the first-level, second-level, and third-level classification levels, respectively. In other words, in terms of the percentage differences in material composition ratio, the first-level was smaller than the second-level, and the second-level was smaller than the third-level. The results of the association rule analysis showed that under the third-level classification, there were many effective association rules, and 27 core groups and 34 specific groups of chemical components were obtained based on these rules. 15 decisive groups were obtained from the feature selection results. Multinomial logistic regression analysis was used to successfully establish a cold and hot properties identification model with an overall accuracy of 89%. The material basis of cold and hot properties of TCMs in Lamiaceae is different and intersect with each other. Twenty-seven groups of chemical components, such as bicyclic diterpenes, are the core groups of cold and hot properties, of which 15 groups are the decisive groups. The cold and hot properties are often characterized by the interaction of multiple classes of substances, and a single class of substances often cannot be used to characterize the properties. The organic combination of multiple classes of substances is the material basis of cold and hot properties.

ABSTRACT

Objective: To explore the phonological processes in initial consonants of Putonghua-speaking children in Jiangsu urban areas. Methods: A status survey was applied. From December 2014 to September 2015, a stratified random sampling method was used to select 958 children aged 1 to 6 years with Putonghua as their mother tongue in the urban area of Nanjing, Changzhou, Yangzhou and Xuzhou to examine their phonological performance. Speech samples were collected by the method of picture naming. The children were divided into 9 age groups (1.5-<2.0, 2.0-<2.5, 2.5-<3.0, 2.5-<3.0, 3.0-<3.5, 3.5-<4.0, 4.0-<4.5, 5.0-<6.0, 6.0-<7.0 years). Descriptive analysis method was used to analyze the phonological processes in initial consonants at different age groups. Results: Among the 958 children, there were 482 boys and 476 girls. The age of the children was (3.8±1.4) years. The number of children in the 9 age groups (1.5-<2.0, 2.0-<2.5, 2.5-<3.0, 2.5-<3.0, 3.0-<3.5, 3.5-<4.0, 4.0-<4.5, 5.0-<6.0, 6.0-<7.0 years) is 100, 110, 110, 114, 114, 114, 111, 119, and 66, separately. The process of substitution was found in the speech of 701 children (73.2%), syllable structure simplification was found in 194 children (20.3%), distortion was found in 41 children (4.3%), and assimilation was found in 17 children (1.8%). Among these 4 types of processes, the occurrence of substitution was highest in all the age groups, ranging from 30.3% (20/66) to 94.5% (104/110). The occurrence of syllable structure simplification ranged from 27.3% (30/110) to 91.0% (91/100) in the age groups of 1.5-<3.0 years and 0.9% (1/114) to 7.9% (9/114) in the age groups of 3.0-<7.0 years. The occurrence of distortion ranged from 7.3% (8/110) to 19.1% (21/110) in the age groups of 1.5-<3.0 years and 0 (0/114) to 2.7% (3/111) in the age groups of 3.0-<7.0 years. The occurrence of assimilation was very low in all age groups, ranging from 0 (0/114) to 3.0% (3/100) among all age groups. For substitution, the occurrence order of mainly individual processes from high to low was listed as follows: retroflexion 35.4% (339/958), deretroflexion 31.6% (303/958), lateralization 27.9% (267/958), stopping 17.8% (171/958), backing 14.2% (136/958), palatalization 10.9% (104/958), fronting 10.6% (102/958), and nasalization 5.8% (56/958). From the 4.0-<4.5 years of age group onwards, the phonological processes in initial consonants all met suppression criteria (the occurrence of processes was reduced to<10%) except retroflexion, deretroflexion, and lateralization. Conclusions: The processes of syllable structure simplification and distortion mainly appears in the early stage of speech sound development, while substitution is the major form of phonological pattern in initial consonants found in developmental speech errors. By 4 years of age, phonological processes in initial consonants almost disappear. The remaining processes that persisted for a longer period of time are retroflexion, deretroflexion, and lateralization.

ABSTRACT

Objective To investigate the clinical characteristics of drug-induced liver injury caused by anti-tuberculosis drugs in newly treated pulmonary tuberculosis patients with hepatitis B virus (HBV). Methods A total of 133 patients with pulmonary tuberculosis and HBV who were treated in Zhuzhou Central Hospital from January 2018 to early January 2022 were selected, and all were treated with conventional anti-tuberculosis 2HRZE/4HR regimen. According to the liver injury, the patients were divided into liver injury group and no liver injury group. Univariate analysis was used to analyze the related factors of liver injury caused by anti-tuberculosis drugs, and multivariate logistic regression analysis was used to analyze the independent risk factors of liver injury caused by anti-tuberculosis drugs. Results Among 133 cases of newly treated pulmonary tuberculosis patients with HBV, 24 cases had liver injury caused by anti-tuberculosis drugs, accounting for 18.05%; 109 patients had no liver injury caused by anti-tuberculosis drugs, accounting for 81.95%. Univariate analysis showed that there were significant differences in smoking history, drinking history, diabetes history, hypertension history, anti-tuberculosis treatment plan, malnutrition, and use of hepatoprotective drugs between the liver injury group and the no liver injury group (P<0.05). Multivariate logistic regression analysis showed that smoking history, drinking history, diabetes history, hypertension history, PZA-containing regimen, malnutrition, and no use of hepatoprotective drugs were independent risk factors for liver injury caused by anti-tuberculosis drugs. Conclusion Smoking history, drinking history, diabetes history, hypertension history, PZA-containing regimen, malnutrition, and no use of hepatoprotective drugs are the risk factors for drug-induced liver injury caused by anti-tuberculosis drugs in newly treated pulmonary tuberculosis patients with HBV.

ABSTRACT

Objective:To investigate the clinic opathological features, treatment and prognosis of children newly diagnosed with ependymoma.Methods:Clinical data of 127 pediatric ependymoma (EPN) patients (0-16 years old) treated with tumor resection and postoperative radiotherapy at Xinhua Hospital Affiliated to Shanghai Jiao Tong University between 2001 and 2021 were retrospectively analyzed. Among them, 53 children were female and 74 were male. Local control (LR), event-free survival (EFS) and overall survival (OS) rates were analyzed by Kaplan-Meier method. The relationship between clinic opathological factors and clinical prognosis, and the effect of treatment on clinical prognosis of patients were analyzed by Cox proportional hazards model.Results:At a median follow-up time of 29 months (3-251 months), the 3-year OS and EFS rates were 89.5% and 71.5%, respectively. For patients undergoing incomplete resection followed by postoperative adjuvant radiotherapy, the 3-year LR, OS and EFS rates were 78.3%, 65.8% and 85.7%, respectively. A total of 43 children were aged <3 years old when diagnosed and 84 aged ≥3 years old. The interval time between surgery and radiotherapy in children aged <3 years old was 91 d, and 35.5 d in those aged ≥3 years old ( P<0.001). For patients <3 years old, the median EFS was 90 months when initiating radiotherapy within ≤70 d after surgery, compared to 43 months for those who initiated radiotherapy at >70 d after surgery ( P=0.053). According to fifth edition of the WHO classification of tumors of the central nervous system (WHO CNS5), 39 children were classified as posterior fossa ependymoma group A (PFA group). The OS and EFS rates in the PFA group were significantly less than those in other groups (3-year OS rate were 69.2% vs. 94.6%, P<0.001; 3-year EFS rate were 46.9% vs. 79.1%, P<0.001). In the PFA group, 12 patients received postoperative adjuvant chemotherapy, 14 did not receive chemotherapy, and whether chemotherapy was given was unknown in 13 cases. No significant differences were observed in OS and EFS between patients treated with and without chemotherapy ( P=0.260, P=0.730). Univariate Cox analysis showed that tumor location and WHO CNS5 molecular classification were significantly associated with EFS, and WHO CNS5 molecular classification was significantly correlated with OS. Multivariate Cox analysis showed that tumor location in the posterior fossa was an independent risk factor for EFS ( HR=2.72, 95% CI=1.1~6.71, P=0.03). Conclusions:Patients newly diagnosed with pediatric ependymoma can obtain favorable survival after surgery combined with postoperative adjuvant radiotherapy. Patients with residual tumors can achieve favorable LC and survival after postoperative adjuvant radiotherapy. Delaying of radiotherapy tends to lead to poor survival for patients aged <3 years old when diagnosed. Children in the PFA group obtain worse prognosis compared to their counterparts in other groups. The tumor location in the posterior fossa is an independent risk factor for pediatric ependymoma.

ABSTRACT

Objective:To quantitatively evaluate and compare the morphology and dynamics parameters of mitral valve devices in patients with atrial functional mitral regurgitation (AFMR) and ventricular functional mitral regurgitation (VFMR) by real-time three-dimensional ultrasound, in order to provide theoretical basis for diagnosis and clinical treatments of the two types of regurgitation patients.Methods:A retrospective study was conducted on 20 AFMR patients (AFMR group) and 20 VFMR patients (VFMR group) who underwent transesophageal echocardiography at Wuhan University People′s Hospital from May to November 2022. Additionally, 20 patients who underwent transesophageal echocardiography at our hospital during the same period due to patent foramen ovale or non cardiac surgery monitoring were selected as the control group. All subjects were measured mitral annulus anteroposterior diameter (AP diameter), anterolateral posteromedial diameter (ALPM diameter), anteroposterior diameter/anterolateral posteromedial diameter (AP/ALPM), commissural width (CW), annular area (AA), annular circumference (AC), annular height (AH), coaptation depth (CD), tenting volume (TV), non-planar angle (NPA) and posterior leaflet angle at isovolumic relaxation time, early diastole, mid diastole, late diastole, isovolumic contraction time, early systole, mid systole, and late systole. The total change rate and systolic change rate of the above parameters were calculated, the differences in structure and dynamic changes of the mitral valve device among three groups were compared, and the correlations between the change rate of mitral annular parameters and left ventricular long axis strain (GLS) were analyzed.Results:①The GLS of three groups were as follows: control group>AFMR group>VFMR group, and the differences between the groups were statistically significant (all P<0.05). ②Static structure: The AP diameter, ALPM diameter, AA, AC, and total leaflet area (TLA) of the AFMR group and VFMR group were significantly larger than those of the control group (all P<0.05), but there was no statistically significant difference between the AFMR group and VFMR group (all P>0.05). Compared with the other two groups, the TV, CD, and posterior leaflet angle of the VFMR group were significantly increased, exhibiting the mitral valve tethering; the control group had the largest AH/CW and the deepest saddle shape; the AFMR group had the smallest TLA/AA and the least mitral valve remodeling; there was no statistically significant difference in the junction area among the three groups (all P>0.05). ③Dynamic changes: AP diameter, ALPM diameter, AA and AC in the control group showed regular changes throughout the cardiac cycle, gradually decreased from isovolumic relaxation time to late diastole, and gradually increased from isovolumic contraction time to late systole; The changes in the above parameters in the AFMR and VFMR groups appeared more disordered. In addition, compared with the control group, the total change rate and systolic change rate of AP diameter in the AFMR group were significantly reduced, but the total change rate of ALPM diameter was significantly increased (all P<0.05). ④The total change rate of AA, ALPM diameter and AP diameter were moderately correlated with GLS ( r=0.353, P=0.006; r=-0.304, P=0.018; r=0.300, P=0.020), while the systolic change rate of posterior leaflet angle was weakly correlated with GLS ( r=0.267, P=0.039). Conclusions:There are differences in the morphology and dynamics parameters of mitral valve device in patients with AFMR and VFMR.Different clinical strategies can be used for the two kinds of functional mitral regurgitation.

ABSTRACT

Objective:To explore the prognostic predictive value of deep neural network (DNN) assisted myocardial contrast echocardiography (MCE) quantitative analysis of ST-elevated myocardial infarction (STEMI) patients after successful percutaneous coronary intervention(PCI).Methods:A retrospective analysis was performed in 97 STEMI patients with thrombolysis in myocardial infarction-3 flow in infarct vessel after primary PCI in Renmin Hospital of Wuhan University from June to November 2021. MCE was performed within 48 h after PCI. Patients were followed up to 120 days. The adverse events were defined as cardiac death, hospitalization for congestive heart failure, reinfarction, stroke and recurrent angina. The framework consisted of the U-net and hierarchical convolutional LSTMs. The plateau myocardial contrast intensity (A), micro-bubble rate constant (β), and microvascular blood flow (MBF) for all myocardial segments were obtained by the framework, and then underwent variability analysis. Patients were divided into low MBF group and high MBF group based on MBF values, the baseline characteristics and adverse events were compared between the two groups. Other variables included biomarkers, ventricular wall motion analysis, MCE qualitative analysis, and left ventricular ejection fraction. The relationship between various variables and prognosis was investigated using Cox regression analysis. The ROC curve was plotted to evaluate the diagnostic efficacy of the models, and the diagnostic efficacy of the models was compared using the integrated discrimination improvement index (IDI).Results:The time-cost for processing all 3 810 frames from 97 patients was 377 s. 92.89% and 7.11% of the frames were evaluated by an experienced echocardiographer as "good segmentation" and "correction needed". The correlation coefficients of A, β, and MBF ranged from 0.97 to 0.99 for intra-observer and inter-observer variability. During follow-up, 20 patients met the adverse events. Multivariate Cox regression analysis showed that for each increase of 1 IU/s in MBF of the infarct-related artery territory, the risk of adverse events decreased by 6% ( HR 0.94, 95% CI =0.91-0.98). There was a 4.5-fold increased risk of adverse events in the low MBF group ( HR 5.50, 95% CI=1.55-19.49). After incorporating DNN-assisted MCE quantitative analysis into qualitative analysis, the IDI for prognostic prediction was 15% (AUC 0.86, sensitivity 0.78, specificity 0.73). Conclusions:MBF of the area supplied by infarct-related artery after STEMI-PCI is an independent protective factor for short-term prognosis. The DNN-assisted MCE quantitative analysis is an objective, efficient, and reproducible method to evaluate microvascular perfusion. Assessment of culprit-MBF after PCI in STEMI patients adds independent short-term prognostic information over qualitative analysis.It has the potential to be a valuable tool for risk stratification and clinical follow-up.

ABSTRACT

Objective:To investigate the current smoking status and smoking abstinence self-efficacy of stroke smoking patients, to clarify the factors associated with the smoking abstinence self-efficacy in stroke patients, and to provide a theoretical basis for subsequent targeted interventions and guidance for smoking cessation.Methods:A total of 196 stroke patients admitted to the Neurology Department of Tianjin Huanhu Hospital from September to December in 2021 were surveyed adopted cross-sectional survey method by the General Information Questionnaire, the Fagerstrom Test for Nicotine Dependence, the Tobacco Hazard Perception Score, and the Smoking Abstinence Self Efficacy Scale. Multiple linear regression was used to analyze the factors associated with patients' smoking abstinence self-efficacy.Results:The overall score of self-efficacy for smoking in stroke patients was (20.78 ± 6.47), and the scores of each dimension in descending order were habit/addiction, negative/emotional and positive/social situations. Multiple linear regression analysis showed that occupation, nicotine dependence score and cognition score of tobacco harm were the influencing factors of smoking abstinence self-efficacy, which could explain 37.4% variation of smoking abstinence self-efficacy.Conclusions:The self-efficacy level of smoking patients with stroke needs to be improved, and helping patients to improve their perception of tobacco harm and reduce their nicotine dependence can improve their self-efficacy level to increase the success rate of smoking cessation, thus reducing or even quitting the health risks caused by smoking behavior.

ABSTRACT

Exosomes are nanoscale extracellular vesicles that are secreted by a variety of cells in the body. They carry particular miRNA, protein molecules, transcription factors, and other information molecules, and they play a role in the pathophysiological regulation of a number of diseases in the body. Exosomes can persist steadily in biological tissues and bodily fluids. Exosomes have quickly advanced in ophthalmology in recent years due to the extensive studies of exosomes in a variety of fields, such as diabetic retinopathy, age-related macular degeneration, autoimmune uveitis, corneal disease, glaucoma, and other diseases. The number of people who are blind caused by diabetic retinopathy is rising as living standards rise. However, it is still unclear how diabetic retinopathy works. In recent years, many studies have found that exosomes play an important role in diabetic retinopathy. In this paper, the most recent developments in exosome studies as they relate to the pathogenesis and progression of diabetic retinopathy are reviewed.

ABSTRACT

ObjectiveTo investigate the prevalence of overweight or obesity in community patients with schizophrenia in Shanghai and to explore the related factors. MethodsStratified cluster sampling method was used and the general condition, physical examination and laboratory examination data of patients with schizophrenia who voluntarily participated in 2020 free health examination of National Basic Public Health Service were analyzed. ResultsA total of 3 200 patients were included into the study ,and the prevalence of overweight and obesity was 36.75% and 17.19%, respectively. Multivariate logistic regression analysis indicated that age between 40 and 60 (OR=1.333, 95%CI: 1.030‒1.724), intake of first-generation antipsychotics (OR=1.413, 95%CI: 1.112‒1.796), intake of second-generation antipsychotics (OR=1.573, 95%CI: 1.288‒1.921), high-normal blood pressure (OR=1.549, 95%CI: 1.245‒1.927), high-abnormal blood pressure (OR=2.824, 95%CI: 2.204‒3.619), elevated ALT (OR=1.874, 95%CI: 1.386‒2.535), elevated FBG (OR=1.270, 95%CI: 1.066‒1.513), and elevated TG (OR=1.652, 95%CI: 1.335‒2.044) were the related factors that associated overweight or obesity in patients with schizophrenia. ConclusionOverweight and obesity are highly prevalent among community patients with schizophrenia in Shanghai. Age between 40 and 60, taking first-generation and second-generation antipsychotics, blood pressure higher than 120/80 mmHg, elevated ALT, elevated FBG, and elevated TG are associated with overweight or obesity in patients with schizophrenia. To provide personalized health guidance, medical staff in primary health care institutions should pay more attention to high-risk groups of overweight and obesity in schizophrenia patients at annual physical examination.

ABSTRACT

Male infertility is a significant cause of psychosocial and marital distress in approximately 50% of couples who are unable to conceive, with male factors being the underlying cause. Guijiajiao (Colla Carapacis et Plastri, CCP) is a Traditional Chinese Medicine commonly used to treat male infertility. The present study aimed to investigate the potential mechanisms underlying the preventive effects of CCP on male infertility. An infertile male rat model was established using cyclophosphamide (CTX), and CCP was administered for both treatment and prevention. Fecal microbiota transplantation (FMT) was also performed to explore the role of gut microbiota in the CCP-mediated prevention of male infertility in rats. Sperm motility and concentration were determined using a semi-automatic sperm classification analyzer. Subsequently, histopathological analysis using HE staining was performed to examine the changes in the small intestine and testis. Moreover, the serum levels of lipopolysaccharide (LPS) and testosterone were measured by ELISA. In addition, immunohistochemistry was conducted to detect CD3 expression in the small intestine, while RT-qPCR was employed to assess the expressions of interleukin-1 beta (IL-1β), cluster of differentiation 3 (CD3), Monocyte chemoattractant protein-1 (MCP-1), and C-X-C motif chemokine ligand 10 (CXCL-10) in the small intestine and epididymis. Finally, gut microbiota was analyzed by 16S rRNA sequencing. CCP improved sperm motility, number, and concentration in CTX-induced infertile male rats. CCP increased the serum testosterone level, inhibited the immune cell infiltration of the intestinal lamina propria, and promoted the aggregation of CD3+ T cells in CTX-induced male infertility rats. CCP also inhibited the expressions of MCP-1, CXCL-10, and IL-1β in the epididymis of male infertility rats. At the genus level, CTX led to a reduction in the abundance of Lactobacillus, Clostridia_UCG.014, and Romboutsia in the intestinal tract of rats. In contrast, CCP decreased the abundance of Ruminococcus and increased the abundance of Romboutsia in infertile male rats. Additionally, FMT experiments proved that the gut microbiota of CCP-treated rats facilitated testicular tissue recovery and spermatogenesis while also reducing the serum LPS level in infertile male rats. CCP improves the spermatogenic ability of infertile male rats by restoring gut microbiota diversity and inhibiting epididymal inflammation.

ABSTRACT

Studies have shown that targeting xanthine oxidase (XO) can be a feasible treatment for fructose-induced hyperuricemia and hyperglycemia. This study aimed to evaluate the dual regulatory effects and molecular mechanisms of diacylated anthocyanins from purple sweet potato (diacylated AF-PSPs) on hyperglycemia and hyperuricemia induced by a high-fructose/high-fat diet. The body weight, organ index, serum biochemical indexes, and liver antioxidant indexes of mice were measured, and the kidneys were observed in pathological sections. The relative expression levels of messenger RNAs (mRNAs) of fructose metabolism pathway enzymes in kidney were detected by fluorescent real-time quantitative polymerase chain (qPCR) reaction technique, and the expression of renal transporter protein and inflammatory factor pathway protein was determined by immunohistochemistry (IHC) technique. Results showed that diacylated AF-PSPs alleviated hyperuricemia in mice, and that this effect might be related to the regulation of liver XO activity, lipid accumulation, and relevant renal transporters. Diacylated AF-PSPs reduced body weight and relieved lipid metabolism disorder, liver lipid accumulation, and liver oxidative stress, thereby enhancing insulin utilization and sensitivity, lowering blood sugar, and reducing hyperglycemia in mice. Also, diacylated AF-PSPs restored mRNA levels related to renal fructose metabolism, and reduced kidney injury and inflammation. This study provided experimental evidence for the mechanisms of dual regulation of blood glucose and uric acid (UA) by diacylated AF-PSPs and their utilization as functional foods in the management of metabolic syndrome.

ABSTRACT

Anaplastic lymphoma kinase (ALK) is a receptor tyrosine kinase and its rearrangements occur in non-small cell lung cancer (NSCLC), resulting in signal dysregulation in kinase domain. As a new generation of potent ALK tyrosine kinase inhibitors (TKIs), Brigatinib was approved in China in March 2022 as a treatment for locally advanced or metastatic NSCLC patients with ALK rearrangement positive. Brigatinib significantly improved the survival, cranial efficacy and quality of life compared to Crizotinib in clinical trials. Brigatinib is generally well tolerated. Brigatinib has been one of the preferred treatments and an addition of options in ALK-rearranged NSCLC. Pulmonary toxicity is one of the adverse effects observed during the treatment of TKIs and deserves the intense attention of clinicians, despite of its low incidence rate. Pulmonary toxicity reported during the treatment of Brigatinib has shown distinct clinical presentations, such as early-onset (median time to onset, 2 days) and rapid tolerance and reversibility of symptoms. In view of this, the concept of early-onset pulmonary events (EOPEs) was proposed and established during the submission for regulatory review and approval. We focused on clinical characteristics, potential mechanism of etiology, and management strategies of EOPEs to provide clinicians evidence for better clinical decision support.

ABSTRACT

Objective:To explore the effect of narrative medicine course on the empathy ability and comprehensive ability training of residents in the standardized residency training in municipal hospitals.Methods:A narrative medicine group was set up in a municipal hospital, and a anarrative medical course of 2 months of narrative theory teaching and 4 months of clinical practice education was carried out among 42 residents. The Chinese version of the Interpersonal Response Index Scale (IRI-C) was used to measure the empathy ability at 4 time points (before intervention, 2 months after theory education, 2 months after practice, and 4 months after practice). The effect of narrative medicine courses was evaluated through the satisfaction questionnaire survey, parallel medical record writing and the first-time pass rate of Medical Practitioner Qualification Examination. SPSS 25.0 was used to analyze the variance of one-way repeated measurement.Results:The empathy ability of 42 residents was significantly improved. The empathy score after 2 months after practice was higher than that before intervention and after the theoretical course ( P < 0.05), while the empathy score after 4 months of practice was higher than that before intervention and after the theoretical course ( P < 0.05). The most popular theoretical teaching forms among residents were interactive theoretical teaching (64.29%, 27/42), video viewing (59.52%, 25/42), and situational simulation (52.38%, 22/42). The comprehensive abilities of parallel medical record writing and podium performance among residents were improved. Passing the Medical Practitioner Qualification Examination is a necessary condition for passing the residency training program. The first-time pass rate of the Qualification Examination for the residents was 72.00% (18/25), which was higher than that of the residents who were not recruited during the same period (64.71%, 11/17). Conclusion:Carrying out narrative medicine education is helpful to improve the empathy ability and comprehensive ability of training residents in municipal hospitals.

ABSTRACT

Thoracic endovascular aortic repair has served as the predominant treatment approach for patients with thoracic aortic diseases. In order to ensure the successful release of the stent as well as a good proximal anchoring effect, it is necessary to preserve or reconstruct the left subclavian supply as much as possible. With the advance of various endovascular assistive technologies, different left subclavian artery revascularization techniques have gained widespread acceptance. So far, techniques include carotid-subclavian bypass or transposition, chimney grafts, fenestrations, branched aortic devices can reconstruct the left subclavian artery and other branch vessels on the arch. This article reviewed the present situation of left subclavian artery reconstruction and the selection of surgical methods of thoracic endovascular aortic repair.

ABSTRACT

Since the pathogenesis of depression is complicated, the therapeutic effects of western medicine are poor accompanied by severe side effects. Chinese medicine has unique advantages in the treatment based on syndrome differentiation and contains many effective components against depression, including flavonoids, terpenes, phenylpropanoids, quinones, and alkaloids. These chemical components can delay the course of the disease, improve the curative effect, and reduce side effects of western medicine by regulating the biochemical abnormalities of monoamine neurotransmitters, brain tissue protein content, and internal environment as well as energy metabolism to make the treatment of Chinese medicine highlighted and recognized. This study systematically reviewed the effective components and mechanisms of anti-depressive Chinese medicine to inspire the rational development and utilization of new Chinese medicines against depression.

ABSTRACT

ObjectiveTo explore the differences in the protective effects of five formulas for promoting blood circulation and removing blood stasis on the aortic endothelial cells of New Zealand rabbits with heart blood stasis syndrome. MethodEighty New Zealand rabbits were randomly divided into a normal group (n=10) and an experimental group (n=70). The heart blood stasis syndrome model was induced by starvation combined with a high-fat diet and adrenaline in the rabbits of the experimental group. Subsequently, the model rabbits were randomly divided into a model group, a Xuefu Zhuyutang group (3.55 g·kg-1·d-1), a Taohong Siwutang group (2.66 g·kg-1·d-1), a Danshenyin group (1.962 g·kg-1·d-1), a Huoluo Xiaolingdan group (2.80 g·kg-1·d-1), a Shixiaosan group (0.56 g·kg-1·d-1), and a c-Jun N-terminal kinase (JNK) inhibitor (SP600125, 5 μg·kg-1)group. The normal group and the model group received the same amount of distilled water. The rabbits in five Chinese medicine groups were treated correspondingly by gavage, and those in the SP600125 group were injected with 0.5 mL of SP600125-dimethyl sulfoxide diluent. After the treatment, the aorta was collected, and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay was used to detect the apoptosis of aortic endothelial cells. The enzyme-linked immunosorbent assay (ELISA) was used to detect serum levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6). Western blot was used to detect the protein expression of JNK, phosphorylated JNK (p-JNK), B-cell lymphoma-2 (Bcl-2), Bcl-2-associated X protein (Bax), cysteinyl aspartate-specific protease-9 (Caspase-9), and cysteinyl aspartate-specific protease-3 (Caspase-3) in aortic tissues. Real-time fluorescence-based quantitative polymerase chain reaction (Real-time PCR) was used to detect the mRNA levels of JNK, Bcl-2, Bax, Caspase-9, and Caspase-3 in aortic tissues. ResultFive formulas could improve the apoptosis of aortic endothelial cells to varying degrees. To be specific, Xuefu Zhuyutang and Taohong Siwutang were optimal in efficacy, followed by Huoluo Xiaolingdan, Shixiaosan, and Danshenyin, and SP600125 was the worst (P<0.05, P<0.01). Five formulas could reduce the content of TNF-α and IL-6 (P<0.05, P<0.01), down-regulate the protein expression levels of JNK, p-JNK, Bax, Caspase-9, and Caspase-3 (P<0.05, P<0.01), decrease the mRNA expression levels of JNK, Bax, Caspase-9, and Caspase-3 (P<0.05, P<0.01), and up-regulate the protein and mRNA expression levels of Bcl-2 (P<0.05, P<0.01). ConclusionFive formulas can all reduce the apoptosis of aortic endothelial cells in New Zealand rabbits with heart blood stasis syndrome with different efficacies. It may be related to the different effects of five formulas on the JNK signaling pathway.

ABSTRACT

ObjectiveTo explore the common syndromes of patients with cerebral infarction in rural areas of eastern Henan based on latent structure model and factor analysis,and provide reference for clinical differentiation of cerebral infarction. MethodThe data samples of patients with cerebral infarction in rural areas in eastern Henan were preprocessed. With Lantern 5.0 of latent structure method and LTM-EAST algorithm of two-step latent tree analysis, the manifest variable latent structure model of related symptoms was built to interpret different latent nodes, and common syndromes of cerebral infarction were obtained via comprehensive cluster analysis. SPSS 20.0 was used for factor analysis and cluster analysis of related symptoms to infer the distribution of syndrome types. ResultThe data of 888 patients with cerebral infarction were included, involving symptoms, tongue and pulse (88 in total). The 65 symptoms with a frequency of ≥5% were constructed into a latent structure model, and 31 latent variables were obtained. The Bayesian information criterion (BIC) score was -15 367.17. Based on professional knowledge, s6 common syndrome types were found, namely, syndrome of upward disturbance of wind-fire, Qi deficiency and blood stasis syndrome, syndrome of phlegm and blood stasis blocking collaterals, syndrome of phlegm-heat and fu-organ excess, syndrome of wind phlegm obstructing collaterals, and syndrome of stirring wind due to yin deficiency. In factor analysis, the symptoms with a frequency of >10% were selected, and 13 common factors were obtained and used for systematic cluster analysis. And 5 syndrome types were inferred: syndrome of wind phlegm obstructing collaterals, syndrome of phlegm-heat and fu-organ excess, Qi deficiency and blood stasis syndrome, syndrome of combined phlegm and blood stasis, and syndrome of yin deficiency and internal heat. According to the determination criteria of syndrome types in traditional Chinese medicine (TCM), 6 common syndrome types of cerebral infarction were finally determined. ConclusionAccording to the severity of the disease, the common syndromes of patients with cerebral infarction in rural areas of Eastern Henan were divided into the following categories: apoplexy involving channel and collateral: syndrome of upward disturbance of wind fire, syndrome of wind phlegm obstructing collaterals, and syndrome of stirring wind due to yin deficiency. Apoplexy involving zang and fu-viscera: syndrome of phlegm-heat and fu-organ excess, and syndrome of phlegm and blood stasis blocking collaterals. Recovery period: Qi deficiency and blood stasis syndrome. This study was basically consistent with the syndrome law in TCM theory, and provided reference for further establishing syndrome diagnostic criteria of cerebral infarction.
