Objective To evaluate the therapeutic effect of new oral care method for the treatment of swallowing disturbance after cerebral apoplexy. Methods A total of 50 post-apoplexy patients with swallowing disturbance were evenly randomized into treatment group and control group, 25 in each group. Both groups were given routine rehabilitation training for recovering swallowing function, and the rehabilitation training covered fundamental training, swallowing training, and food in-take training. And additionally, the control group was given routine oral care, and the treatment group was given new oral care method which included the stimulation on K point, cold Yin He gargle stimulation and focal application of herbal medicine buccal droplets. Two weeks later, water swallow test results were grading for evaluation of the therapeutic effect of the two groups. Results (1) After treatment for 2 continuous weeks, the water swallow test results were classified into grades 1 and 2 in 23 cases of the treatment group and in 17 of the control group, indicating that the treatment group had better effect on improving swallowing function ( P<0.01). ( 2) The total effective rate was 92.0% in the treatment group, higher than 68.0% in the control group ( P<0.01). Conclusion New oral care method has better effect on relieving swallowing disturbance than routine oral care for the treatment of swallowing disturbance after cerebral apoplexy.

Forty-two patients with type 2 diabetes (DM group),23 type 2 diabetic patients with unstable angina pectoris (DM + UAP group),and 36 healthy subjects (control group) were enrolled in this study.Serum samples were collected for determining serum concentrations of vascular endothelial growth factor (VEGF),Angiopoietin (Ang)-1,Ang-2,angiogenin,angiostatin,basic fibroblast growth factor,and platelet-derived growth factor-BB using protein array technology.The results showed that there were no significant differences in serum concentrations of all 7 angiogenic factors between control group and DM group.Whereas,serum concentrations of V EGF and Ang-2 were significantly increased in DM + UAP group compared with control group [(3 532.10 ± 1 813.72vs 2 444.50 ± 1 152.21) pg/ml,(286.90-± 217.01 vs 171.92 ± 106.63) pg/ml,both P＜0.01].Pearson's correlation analysis revealed that serum concentrations of all 7 angiogenic factors were not related to HbA1C,fasting and 2 h postprandial plasma glucose,triglycerides,high density lipoprotein cholesterol,as well as low density lipoprotein cholesterol.

Objective To detect the changes in serum concentrations of angiogenic factors in patients with unstable angina pectoris.Methods A total of 57 patients with unstable angina pectoris were eligible for study and divided into diabetes group (n =23) and non-diabetes group (n =34).Exclusion criteria included complicated diseases,symptomatic peripheral vascular diseases,renal or liver diseases,cerebral embolism and evidence of ongoing infection.Another 36 age-matched healthy subjects from medical examination center were enrolled as control group.Serum samples were collected,and serum concentrations of vascular endothelial growth factor (VEGF),angiopoietin-1,angiopoietin-2,angiogenin,angiostatin,basic fibroblast growth factor (bFGF) and platelet-derived growth factor-BB (PDGF-BB) were measured by using cytokine array technology.The data were analyzed by independent-samples t test with the SPSS 13.0statistic software package.Results Compared with the control group,the serum concentrations of VEGF and angiopoietin-2 were significantly increased in patients with unstable angina pectoris (both P ＜ 0.01).Whereas,no significant differences in serum concentrations of angiogenin,angiopoietin-1,angiostatin,bFGF,and PDGF-BB were detected between control group and patient groups.There were no significant differences in serum concentrations of above all 7 biomarkers between diabetes group and non-diabetes group.Conclusions Serum concentrations of VEGF and angiopoietin-2 were increased in patients with unstable angina pectoris,and diabetes didn' t affect the increases in serum concentrations of VEGF and angiopoietin2 caused by unstable angina pectoris.

ObjectiveTo investigate the clinical value of ultrasound-guided percutaneous drainage in the treatment of liver abscess from the aspects of laboratory markers and size of abscess. MethodsA total of 79 patients with liver abscess who underwent ultrasound-guided percutaneous drainage in Department of Gastroenterology in Northern Jiangsu People’s Hospital from January 2013 to August 2018 were enrolled, among whom 36 patients who were lost or transferred, abandoned treatment, had an age pf ＜18 years, or were not followed up in the outpatient service were excluded. A total of 43 patients were finally included in the retrospective study. The t-test was used for comparison of continuous data between groups, and the chi-square test was used for comparison of categorical data between groups. ResultsAll 43 patients achieved a one-time success of puncture and placement of drainage tube.

ConclusionThe expression of OX40/OX40L in peripheral blood increases in patients with AIH, PBC, and their overlap syndrome and decreases after treatment, indicating that the OX40/OX40L pathway is involved in the pathogenesis of the above diseases, and the role of OX40 on the surface of CD8+ T cells may better reflect the treatment outcome.

In this study, the molecular mechanism of Cinnamomi Cortex-Rehmanniae Radix (CR) in the prevention and treatment of osteoporosis (OP) was investigated by integrating compatibility analysis of compound, bioinformatics and metabolomics. The rat OP models were established, and the Micro-CT indexes and pathological sections were comprehensively evaluated. The results showed that compared with the model group, the indexes such as bone mineral density (BMD) and bone volume/tissue volume (BV/TV) were significantly increased after CR treatment (P < 0.05), and the bone trabeculae were arranged into mesh. The results of UHPLC-Q-TOF/MS mainly involved amino acid metabolism, lipid metabolism and estrogen metabolism pathways. Integrating bioinformatics and metabolomics analysis, it was finally found that: ① cinnamic acid and ethylcinnamate inhibit inflammatory factors such as TNF, IL-1β, and IL-13, thereby preventing and treating OP; ② multiple active ingredients of CR target ESR2, PPARG, and CYP19A1, GABRA1 and other targets, regulate cAMP synthesis, AMPK signaling pathway and lipid metabolism, thereby regulating estrogen levels to prevent and treat OP; ③ oleic acid, arachic acid, etc. act on AR, VDR and other targets, and regulate HIF-1 signaling pathway and AGE-RAGE signaling pathway, thereby regulating osteoblasts and osteoclasts, and affecting calcium and phosphorus absorption to maintain bone homeostasis. This study clarified the molecular mechanism of CR in preventing and treating OP from the perspective of multi-directional regulation of inflammatory factors, estrogen and bone homeostasis, and provided theoretical basis for the clinical application of CR and the development of compound. This experiment complied with the ethical standards of animal experiments and was approved by the Animal Ethics Committee of Shaanxi University of Chinese Medicine (No. SUCMDL20210309002).

In this study, the effective substance group and molecular mechanism of Rhei Radix et Rhizoma-Persicae Semen combination (RRR-PS) in activating blood circulation and dispelling blood stasis were investigated by integrating efficacy experiments, network pharmacology and HPLC. The rat model of blood stasis syndrome was established, and the blood rheology index and coagulation four comprehensive evaluation were carried out. The results showed that compared with the model group, the whole blood viscosity, erythrocyte sedimentation rate and erythrocyte aggregation index of the rats in the RRR-PS group were significantly callback (P < 0.01). Network pharmacology found that RRR-PS combination exerted the effect of activating blood circulation and dispelling blood stasis by acting on calmodulin-1 (CALM1), nitric oxide synthase-2 (NOS2), glucocorticoid receptor (NR3C1) and other targets, regulating platelet activation, peroxisome proliferator-activated receptor (PPAR), vascular endothelial growth factor A (VEGF) and other signaling pathways, and found key components: sennoside B, (+)-catechin, emodin, physcion, rhein, aloe-emodin, chrysophanol, gallic acid. HPLC was used to explore the dissolution rate of key components. The results showed that the contents of catechin, emodin, chrysophanol and physcion were significantly increased after RRR-PS combination (P < 0.01). In summary, RRR-PS has a significant effect on promoting blood circulation and removing blood stasis, and its mechanism of action is related to promoting angiogenesis, anti-coagulation, anti-thrombosis and anti-inflammation. The efficacy is related to the change of solvent system and the large dissolution of catechin, emodin, chrysophanol and physcion after the RRR-PS combination. The results of the study can further provide a reference for the follow-up study on the active substances and mechanism of the RRR-PS combination. Animal experiments have been approved by the Experimental Animal Committee of Shaanxi University of Traditional Chinese Medicine (No. SUCMDL20210309002).
