Professor LI Ying-cun believes that pediatric internal injury cough is due to the weakness of lung and spleen and endogenous phlegm. The lung loses dispersing and descending to retrograde and cause cough; spleen deficiency produces phlegm to exist in the lung. The children have delicate organs need strengthening the body resistance, dispersing lung and invigorating spleen, supplementing qi and consolidating the exterior.ZisuDecoction is one of the TCM prescriptions that found from Dunhuang ancient medical prescriptions. Professor LI Ying-cun flexiblely uses this ancient prescription in modern clinic, which has achieved good efficacy in treatment of pediatric internal injury cough.

Objective To investigate the effects of environmental enrichment (EE) on the neurological functions in patients with stroke. Methods From May, 2013 to November, 2015, 76 patients with stroke were selected and randomly divided into control group (n=39) and EE group (n=37). Both groups received routine therapy and the EE group received EE in addition. They were assessed with simplified Fugl-Meyer Assessment (FMA), Montreal Cognitive Assessment (MoCA) and modified Barthel Index (MBI) before and after treatment. Re-sults The scores of FMA, MoCA and MBI increased in both groups after treatment (t>2.339, P<0.05), and the scores of MoCA and MBI in-creased more in the EE group than in the control group (t>2.187, P<0.05). Conclusion EE could promote the recovery of cognitive function and activities of daily living in patients with stroke.

Objective:To evaluate the clinicopathological significance of the expression of the two myeloid cell leukemia-1 isoforms, myeloid cell leukemia-1-long (Mcl-1L) and myeloid cell leukemia-1-short (Mcl-1S) in malignant pleomorphic adenoma (MPA).Methods:A total of 56 patients with MPA treated with surgery, the expression of Mcl-1L and Mcl-1S were detected by quantitative real-time PCR (qPCR) in mRNA level, and by Western blotting in protein level, respectively. The correlation between clinicopathological parameters (gender, age, site, habits, size, node, metastasis, recurrence) was done using the chi-square test. Kaplan-Merier curve was used to analyze the survival in all patients, Log Rank test was performed to observe the difference between groups. Cox′s proportional hazard test was used to identify the factors that were independent predictors of survival. Results:qPCR showed overexpression of Mcl-1L in 66.1%MPA patients (37/56), with significant difference in terms of tumor site, significantly higher expression of Mcl-1L in MPA (parotid gland: 2.21±1.07, sublingual gland: 2.12±1.08, other sites: 1.83±0.81) than benign pleomorphic adenoma tissue (1.00±0.19) ( P<0.01). Western blotting analysis showed significantly higher expression of Mcl-1L in MPA (parotid gland: 1.02±0.43, sublingual gland: 0.71±0.29, other sites: 0.70±0.30) than benign pleomorphic adenoma tissue (0.39±0.08) ( P<0.01). In malignant pleomorphic adenoma patients, high Mcl-1L expression was significantly associated with node positivity ( P=0.045), advanced tumor size ( P=0.002). Kaplan-Meier survival line analysis indicated a significantly lower survival time in Mcl-1L higher-expression patients (24.79±9.71) than lower-expression patients (30.59±9.01) ( P=0.017). Multivariate analysis indicated Mcl-1L to be an independent prognostic factor for MPA ( P=0.002). Conclusions:The studies suggest that overexpression of Mcl-1L is associated with poor prognosis in MPA. Mcl-1L is an independent prognostic factor in malignant pleomorphic adenoma.

"Metaphysics"is a philosophical perspective different from mechanical materialism,and the Chinese philosophy and traditional Chinese medicine's view of the human body as"body-qi-spirit"embodies a"metaphysical"cognitive pattern.This paper takes the content of General Treatise on Causes and Manifestations of All Diseases·Wind Diseases as an example to analyze and compare the cognitive evolution process of wind diseases in General Treatise on Causes and Manifestations of All Diseases.It is argued that the General Treatise on Causes and Manifestations of All Diseases constructs a body model characterized by"metaphysics"where the meridian system connects the entire body to facilitate the flow of qi and blood,with the organs serving as the storage places for essence-qi.Through the analysis of the symptoms of stroke,it reveals the specific application of this body model in the theory of disease mechanisms.The meridian tendons,as the subordinate parts of the meridian system,become the physical basis for the explanation of stroke with their substantive existence.It is thus determined that General Treatise on Causes and Manifestations of All Diseases has perfected the two-layer space of"metaphysical-physical"body structure of the theory of disease pathogenesis,laid the foundation for the theory of disease mechanism with the state of qi and blood as the focus of discussion,and constructed a model of disease diagnosis and treatment,which is"disease-symptom-etiology and pathogenesis-treatment".

Objective:To investigate the effect and relationship of coronary microvascular dysfunction (CMD) on cardiac mechanical indices in patients with non-obstructive coronary artery disease(NOCAD) in the resting state.Methods:This study was a single-center retrospective study. Seventy-nine NOCAD patients who hospitalized in Qilu Hospital of Shandong University from July 2017 to March 2022 were recruited. All patients underwent conventional echocardiography examination and the examination of coronary flow velocity reserved by transthoracic Doppler echocardiography (TTDE-CFVR). Based on the results of TTDE-CFVR, patients were divided into CMD group (CFVR<2.5, 32 cases) and a control group (CFVR≥2.5, 47 cases). Clinical data, routine echocardiographic parameters, regional mechanical indices including regional myocardial work index(RWI) and regional longitudinal strain(RLS), global mechanical indices including left ventricular global longitudinal strain(GLS), global longitudinal strain in the endocardial layer(GLS-endo), global longitudinal strain in the epicardial layer(GLS-epi), left ventricular global work index(GWI), global contractive work(GCW), global waste work(GWW), global work efficiency(GWE) were compared between two groups. Binary logistic regression was used to analyze the risk factors of CMD. ROC curve was used to construct a prediction model for CMD.Results:There was no significant difference in sex ratio, BMI, smoking history, diabetes, hypertension and dyslipidemia between CMD group and control group. Age was significantly higher in the CMD group than in the control group. RWI, GWI, GCW, GWE and the absolute values of RLS, GLS, GLS-endo and GLS-epi were significantly lower in the CMD group than in the control group. Logistic regression analysis showed that the decrease of absolute value of GLS was an independent risk factor for the CMD( OR=1.335, 95% CI=1.041-1.713, P=0.023). ROC curve showed that myocardial strain-related indexes had a good decrease value for the CMD. Conclusions:For patients with NOCAD, the presence of CMD is associated with the decrease of left ventricular regional and global systolic function.

BACKGROUND:Exercise has a regulatory effect on intestinal flora dysbiosis,which can effectively protect the beneficial flora and improve the intestinal environment.However,the effect of treadmill exercise on the structure and diversity of intestinal microbial community in Parkinson's disease and the specific mechanism are not clear. OBJECTIVE:Using 16S rDNA technique to analyze the effect of treadmill exercise on the structure and diversity of the intestinal flora of rats with Parkinson's disease,and to investigate the mechanism of non-pharmacological treadmill exercise to improve Parkinson's disease. METHODS:Twelve of the 18 Sprague-Dawley rats were randomly selected to make animal models of Parkinson's disease using unilateral 2-point nigrostriatal injection of 6-hydroxydopamine.The remaining six rats were used as sham-operation group,which were injected with the same dose of saline containing 0.2%ascorbic acid using the same positioning and injection method.After successful modeling,12 rats with Parkinson's disease were randomly divided into model group and treadmill exercise group(n=6 per group).The treadmill exercise group was subjected to a middle and low intensity tread mill exercise,10 m/min,30 minutes per day,5 days per week for 4 weeks.Fresh feces were collected and stored in liquid nitrogen 24 hour after the last exercise session,and the changes in fecal flora were analyzed by 16S rDNA sequencing technique. RESULTS AND CONCLUSION:Treadmill exercise significantly improved behavior and nigrostriatal tyrosine hydroxylase-positive cell expression in rats with Parkinson's disease model and alleviated changes in the structure and diversity of the gut microbial community caused by Parkinson's disease,increased the number of operational taxonomic units and modulated Alpha and Beta diversity in rats.At the phylum and genus levels,the abundance ratio of Firmicutes/Bacteroidetes in the model group decreased compared with the sham-operated group,while beneficial bacteria such as Prevotella,Bacteroides,and Clostridium_XlV increased significantly after treadmill exercise.To conclude,treadmill exercise has a significant modulating effect on behavioral abnormalities,toxic damage to dopaminergic neurons and gut microbial imbalance caused by Parkinson's disease,alleviates the symptoms of flora-related diseases,and has a positive effect on the improvement of Parkinson's disease.

OBJECTIVETo explore the clinical and genetic characteristics of patients with dentatorubro-pallidoluysian atrophy (DRPLA).

METHODSDNA analysis for DRPLA gene was performed in two patients. Clinical features and genetic testing of Chinese DRPLA patients reported in the literature were reviewed in terms of initial symptoms, CAG repeat and age of onset.

RESULTSBoth families were confirmed by genetic analysis. In family 1, the number of CAG repeat in the proband, his brother and his mother was determined respectively as 8/65, 8/53 and 8/18. In family 2, the number of CAG repeat was respectively 13/63, 13/18, 18/52 and 13/13 in the proband, his brother, his father and his mother. The size of the expanded CAG repeats has inversely correlated with the age at onset (P<0.05, r=- 0.555). The age at onset of epilepsy was 10 and that for the onset of ataxia is forty years in initial symptom.

CONCLUSIONThe clinical characteristics of DRPLA include epilepsy, ataxia and cognitive impairment. The initial symptoms are epilepsy in adolescence and ataxia in adults. The size of expanded CAG repeats inversely correlates with the age at onset. The initial symptoms are different with different age of onset. It is difficult to diagnose DRPLA at an early stage.

Objective:To investigate the influence of cognitive-behavior therapy on the psychological status of family members of terminal cancer patients. Method:A total of 60 families of terminal cancer patients were selected and randomly divided into observation group (30 cases) and control group (30 cases). The observation group was treated with cognitive-behavior therapy, while the control group was given general supportive psychological care. The Hamilton Depression Scale ( HAMD) , Hamilton Anxiety Scale ( HAMA) and Pittsburgh Sleep Quality Index ( PSQL) were used to evaluate the family members of the two groups of patients before and after the intervention. Results: Before the intervention, there was no statistical significance difference in the scores of HAMA, HAMD and PSQI between the two groups (P>0. 05). After the intervention, the scores of HAMA, HAMD and PSQI in the observation group were significantly lower than those before the intervention ( P <0 . 05 ); and the scores of HAMA, HAMD and PSQI in the observation group were significantly lower than those in the control group ( P<0 . 05 ) . Conclusion:Cognitive-behavior therapy can significantly improve the negative emotions of depression, anxiety and sleep disorder among family members of terminal tumor patients.

In the past decades, great progress has been made in cartilage regeneration. The traditional techniques for constructing tissue engineering cartilage scaffold mainly include pore agent method (or template method ) , phase separation method, gas foaming method, freeze-drying method , electrospinning method, etc. Cartilage is heterogeneous, and it is difficult for traditional scaffolds to simulate the high anisotropy of cartilage. Therefore, functional regeneration of cartilage is challenging. With the progress of three-dimensional (3D) printing technology, it is possible to prepare functional bionic scaffolds with fine structure and gradient changes through co deposition of biomaterials, cells and active biomolecules, so as to achieve functional cartilage regeneration. This article reviews 3D printing technology of cartilage tissue engineering, and the application of 3D printing technology in cartilage regeneration at different anatomical positions (articular cartilage, auricle cartilage, nasal cartilage) . In addition, the importance of preparing bionic constructs with regional structure gradient and regional composition gradient was discussed. 3D bioprinting technology, 4 D printing techniques, smart biomaterials brought hope for the construction of bionic tissues and organs.
