This study was aimed to find the correlation between amino acid compositions and Cold-Heat Nature of traditional Chinese medicine (TCM) in order to provide basis for the research of TCM natural theory. A total of 17 kinds of amino acid were determined by application before column derivatization reaction and high-perfor-mance liquid chromatography (HPLC) and the tryptophan was determined by UV method. The data were collected for analysis by Fisher method in PAST software. The best statistical identification model was determined. And the Cold-Hot medicine property markers (CHMP-markers) were determined. The results showed that the discriminant function established by Fisher method based on 18 kinds of amino acid contents has good identification ability, and the accuracy of the Fisher discriminant analysis is 82%. Support vector machine (SVM) is the best statistical identification model . The cold and heat markers were analyzed by SVM . The cold nature material bases in-clude Glu, Gly, Arg, Thr, Ala, Tyr, Val, Ile and lys. And the heat nature material bases contain Asp, Ser, His, Pro, Met, Cys, Leu, Phe and Trp. It was concluded that there is relationship between 18 kinds of amino acid contents and the Cold-Heat nature of TCM .

Objective To investigate the relationship between the average amplitude of swallowing-related muscles during pharyngeal swallowing and age and swallow model of healthy adults in different age groups.Methods A total of 200 healthy adults were recruited and divided into 4 age groups:group A (18 ～ 30 years old,n =59),group B (30～50 years old,n=50),group C (50 ～70 years old,n=49) and group D (70 years old,n=40).Surface electromyography was used to acquired the average amplitude of electrical activity of the muscles during three swallow models:resting state,voluntary single swallows of saliva (dry swallowing),voluntary single swallows of 5 ml water at once(wet swallowing)and voluntary single swallows 20 ml water at once.The mean value of the average amplitude of normal adults of different ages were calculated and analyzed.Results ①Intergroup comparison showed no difference in the average amplitude of submental muscles and infrahyoid muscles among the 4 age groups (P ＞ 0.05) in all the three swallowing models ;②Intra-group comparison showed that,there were no statistical differences in the average amplitude of submental muscles among the three swallow models between groups A and B (P ＞ 0.05).In group C,there were no statistical differences between dry swallowing and wet swallowing of 5 ml of water in terms of the average amplitude of submental muscles and infrahyoid muscles during dry swallowing.(P ＞ 0.05),however,but there existed statistical differences in terms of the average amplitude of submental muscles and infrahyoid muscles,when comparing dry swallowing with voluntary single swallowing 20 ml water at once(P ＜ 0.05).The average amplitude of submental muscles and infrahyoid muscles during swallowing of 20 ml water were significantly higher than that during wet swallowing(P ＜0.05).In group D,there was no difference between drying swallow and wet swallowing(P ＞ 0.05)in terms of the mean sEMG amplitude of the muscles,but all lower than swallowing 20 ml of water,with a statistically significant differences(P ＜ 0.05).Conclusions The sEMG amplitude in swallowing-related muscles during pharyngeal swallowing is not related to age,but swallowing models.

Sepsis is a severe systemic inflammatory response syndrome, and is common in the patients with infection, extensive burn injury and major surgery. As it may cause multiple organ dysfunction and septic shock, it is always accompanied with high mortality and poor prognosis. Currently there's no effective medication available for treatment of sepsis. During the process of killing bacteria, the classical antibiotics lead to release of a large quantity of proinflammatory cytokines, such as lipopolysaccharide, which exacerbates the malfunction of immune system. Furthermore, the growing number of multiresistant bacteria present a new challenge to the management of sepsis. Antimicrobial peptides (AMPs) are small, cationic, and amphipathic peptides with broad-spectrum microbicidal activity against bacteria, fungi and viruses. In addition, they also can neutralize endotoxin and suppress inflammatory cascade through multiple immunomodulation, which potentially serves as a promising alternative approach for sepsis treatment. This review briefly summarizes the progress of AMPs in the treatment of sepsis as well as the relevant mechanisms.

Objective:To compare the effects of different doses of atorvastatin on blood lipid and endothelial function in patients with hypertension and carotid plaque.Methods:Ninety-two patients with hypertension and carotid plaque who received treatment from June 2019 to June 2020 were included in this study. They were assigned to receive treatment with either atorvastatin 20 mg (control group, n = 46) or atorvastatin 40 mg (study group, n = 46) for 3 months. Blood lipid level and endothelial function were compared between the two groups. Results:There were no significant differences in sex, age, course of disease, body mass index (BMI) and carotid plaque grading between the two groups (all P > 0.05). Before treatment, there were no significant differences in serum levels of total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) between two groups (all P > 0.05). After treatment, serum levels of TC, TG and LDL-C in each group were significantly decreased compared with before treatment [study group: TC: (5.8 ± 2.3) mmol/L vs. (3.5 ± 1.3) mmol/L, t = 5.904; TG: (2.5 ± 0.8) mmol/L vs. (1.2 ± 0.5) mmol/L, t = 9.346; LDL-C: (5.0 ± 0.4) mmol/L vs. (3.3 ± 0.4) mmol/L, t = 20.382; control group: TC: (5.9 ± 1.8) mmol/L vs. (4.5 ± 1.5) mmol/L, t = 4.052; TG: (2.6 ± 0.3) mmol/L vs. (1.8 ± 0.7) mmol/L, t = 7.125; LDL-C: (4.9 ± 0.5) mmol/L vs. (4.2 ± 0.5) mmol/L, t = 6.714, all P < 0.01). After treatment, serum level of HDL-C in each group was significantly increased compared with before treatment [study group: (0.8 ± 0.5) mmol/L vs. (1.5 ± 0.3) mmol/L, t = 8.142; control group: (0.8 ± 0.4) mmol/L vs. (1.3 ± 0.2) mmol/ L, t = 7.583, both P < 0.01]. After treatment, serum levels of TC, TG and LDL-C in the study group were significantly lower than those in the control group ( tTC = 3.417, tTG = 4.731, tLDL-C = 9.533, all P < 0.01). After treatment, serum level of HDL-C in the study group was significantly higher than that in the control group ( tHDL-C = 3.762, P < 0.01). Before treatment, there were no significant differences in endothelium-dependent (flow mediated dilation, FMD) and endothelium-independent diastolic function (nitroglycerin- mediated dilatation, NMD) between the two groups (both P > 0.05). After treatment, FMD in each group was significantly enhanced compared with before treatment [study group: (7.5 ± 1.8) % vs. (10.9 ± 2.5) %, t = 7.486; control group: (7.7 ± 1.5) % vs. (8.9 ± 2.2) %, t = 3.057; both P < 0.05]. After treatment, FMD in the study group was significantly higher than that in the control group ( t = 4.073, P < 0.01). There was no significant difference in NMD between before and after treatment in the control group. After treatment, NMD in the study group was significantly increased compared with before treatment [(12.5 ± 2.3) % vs. (13.6 ± 2.5) %, t = 2.196, P = 0.031]. Conclusion:Atorvastatin 40 mg once a day can effectively regulate blood lipid level and improve endothelial function in patients with hypertension and carotid plaque, which exhibits superior effects to atorvastatin 20 mg once a day.

Objective To investigate the effect of pretreatment with U75302,antagonist of leukotriene B4 receptor 1 (BLT1),on cisplatin induced acute kidney injury in mice and its immunoregulatory mechanism.Methods Healthy C57BL/6 mice were randomized into four subgroups:1.healthy control group;2.cisplatin group;3.U75302 control group;4.cisplatin + U75302 group,n=6.Group 2 and 4 received intraperitoneal injection of cisplatin (20 mg/kg) on day 0,group 3 and 4received intraperitoneal injection of U75302 (5 μg/mouse) on day 0 and day 2.Mice were sacrificed on the 3rd day and blood and kidney were collected.Renal function and histological changes were estimated,the infiltration of immune cells were determined by flow cytometry,the level of peroxidase (MPO) in kidney were determined by colorimetry,relative expression of TNF-α,IL-1β,CXCL1,CXCL2 were detected by Real-time PCR.Results Compared with healthy control group,levels of BUN,Scr were higher in cisplatin group with serious tubular structural damage.There were more neutrophils,macrophages,CD4+ T lymphocytes,CD8+ T lymphocytes in kidneys of cisplatin group,the level of MPO and relative expression of TNF-α,IL-1β,CXCL1,CXCL2 were also higher in cisplatin group.Compared with cisplatin group,lower BUN [(17.75±1.80) mmol/L vs (42.6±6.66) mmol/L,P ＜0.05],Scr were found in cisplatin+ U75302 group with less tubular structural damage.Meanwhile,U75302 reduced infiltration of neutrophils [(146±13)×103/g vs (296±66) ×103/g,P ＜ 0.05],macrophages [(245± 13)× 103/g vs (420±78)× 103/g,P ＜ 0.05] in the kidney.Levels of MPO [(1.756±0.283) U/g vs (3.308±0.577) U/g,P＜0.05] and relative expression of TNF-α,IL-1β,CXCL1,CXCL2 were also lower.Conclusions BLT1 antagonist U75302 protects mice against AKI induced by cisplatin,and the mechanism is associated with reduced infiltration of inflammatory cells in kidney and the inhibition of kidney inflammation.

Objective:To evaluate the hemodynamic situation of the patients with moyamoya disease using MR perfusion imaging,and to explore the relationship between compensatory collateral circulation and perfusion. Methods:Seventy-two hospitalized patients with moyamoya disease were selected as typical moyamoya disease group,including 37 males and 35 females,aged 10 - 62 years old,all patients underwent cerebral angiography (DSA)and MR perfusion imaging.And 20 patients with out neurological history were used as control group.With mean transit time (MTT)image as a standard,the abnormal perfusion ranges were classified as region of interest (ROI),and the corresponding perfusion parameter values,including cerebral blood flow (CBF),cerebral blood volume (CBV),MTT and time to peak (TTP)were recorded,respectively.The cerebellum was used as a reference in this study,the perfusion parameters were standardized,and the relative ratios of the perfusion parameters (rMTT,rTTP,rCBF,rCBV)were obtained.Results:Compared with control group,the rMTT and rTTP of the patients in typical moyamoya disease group were prolonged and the rCBF was reduced (P <0.05 or P < 0.01), but the rCBV had no obvious difference (P >0.05).②Compared with the contralateral side,the rMTT and rTTP of the suffered side were prolonged,and the rCBF and rCBV were reduced (P < 0.05 or P < 0.01).Compared with chronic onset group,the rCBV and rCBF of the patients in acute onset group were reduced (P <0.05 or P <0.01),but the rMTT and rTTP had no statistically significant difference (P > 0.05).There were no significant differences in all parameters between hemorrhagic moyamoya disease group and ischemia group (P > 0.05 ). Conclusion:MR perfusion imaging can accurately evaluate the hemodynamic condition of moyamoya disease;MTT and TTP hve higher sensitivities than CBF and CBV.MR perfusion imaging can evaluate the compensation of collateral circulation of moyamoya disease and provide the objective basis for the clinician to select the proper surgical timing and the best operation methods.
