ObjectiveTo reveal the active substances and mechanisms of modified Qing'e formula （MQEF） in delaying skin photoaging by ultra-performance liquid chromatography-quadrupole-time of flight mass spectrometry （UPLC-Q-TOF-MS），network pharmacology， and cell experiments. MethodsUPLC-Q-TOF-MS and a literature review were employed to analyze the transdermally absorbed components in mice after the topical application of MQEF. The potential targets of MQEF in treating skin photoaging were retrieved from databases.The compound-potential target network and protein-protein interaction network were constructed to screen the key components and core targets. A photoaging cell model was established by irradiating HaCaT cells with medium-wave ultraviolet B （UVB）. The safe doses of bakuchiol （BAK） and salvianolic acid B （SAB） for treating HaCaT cells and the effects of BAK and SAB on the viability of cells exposed to UVB irradiation were determined by the cell counting kit-8 （CCK-8） method.The reactive oxygen species （ROS） fluorescent probe was used to measure the ROS production in the cells treated with BAK and SAB.The expression levels of genes related to oxidative stress，inflammation，collagen metabolism，and circadian rhythm clock were measured by Real-time PCR. ResultsA total of 24 transdermally absorbed components of MQEF were identified，which acted on 367 potential targets，and 417 targets related to skin photoaging were screened out，among which 47 common targets were predicted as the targets of MQEF in treating skin photoaging. MQEF exerted the anti-photoaging effect via key components such as BAK and SAB，which acted on core proteins such as serine/threonine kinase 1 （Akt1） and mitogen-activated protein kinase 3 （MAPK3） and intervened in core pathways such as the tumor necrosis factor （TNF） and phosphatidylinositol-3-kinase （PI3K）/protein kinase B （Akt） signaling pathways.Compared with the model group，the administration of BAK and SAB increased the survival rate of HaCaT cells （P<0.01），down-regulated the mRNA levels of cyclooxygenase-2 （COX-2），interleukin-6 （IL-6），tumor necrosis factor-α （TNF-α），matrix metalloproteinase-1 （MMP-1），and matrix metalloproteinase-9 （MMP-9） （P<0.01），and up-regulated the mRNA levels of heme oxygenase-1 （HO-1） and NAD（P）H quinone dehydrogenase 1 （NQO-1） （P<0.05，P<0.01） in photoaged HaCaT cells.In addition，it eliminated excess ROS production induced by UVB and up-regulated the mRNA levels of brain and muscle ARNT-like 1 （BMAL1） and circadian locomotor output cycles kaput （CLOCK） associated with circadian clock （P<0.05，P<0.01）. ConclusionMQEF delays skin photoaging through the coordinated effects of various components，multiple targets，and diverse pathways.The key components BAK and SAB in MQEF exhibit anti-photoaging properties，which involve inhibiting oxidative stress，preventing collagen degradation，mitigating inflammation，and maintaining normal skin circadian rhythms by regulating clock gene expression.

Objective:To observe the effectiveness of combining mirror therapy with pneumatic flexible glove training in treating hand dysfunction after a stroke. Its effect on cerebral cortex activation was documented using near-infrared functional imaging of the brain.Methods:A total of 84 stroke survivors with hand dysfunction were randomly divided into a Mirror Group, a Glove Group and a Combined Group, each of 28. In addition to standard rehabilitation training, the Glove Group received 20 minutes of training with a pneumatic soft glove, 5 days per week for 6 consecutive weeks. The Mirror Group received mirror therapy (MT). The Combined Group was given both simultaneously. Before and after the treatment, everyone′s upper limb functioning was evaluated (using the Fugl-Meyer Upper Limb Assessment (FMA-U)), along with their hand motor skills (using the Arm Action Test (ARAT)) and their ability in daily living activities (using the Barthel Index (BI)). Functional near-infrared spectroscopy (fNIRS) was employed to measure any changes in oxygenated hemoglobin (HBO) concentration at 730nm and 850nm wavelengths.Results:The FMA-U, ATAT and BI scores in both the proximal and distal regions of all three groups showed significant improvement after the treatments compared to pre-treatment levels. The combined group demonstrated significantly better distal FMA-U and ARAT scores after the treatment (12.25±8.80 and 20.93±15.68 respectively), outperforming both the glove and mirror groups. The infrared spectroscopy revealed that bilateral SM1 activation, affected-side somatosensory association cortex (SAC) and supplementary motor cortex excitability in both the mirror and combined groups were significantly better than among the glove group after the experiment.Conclusions:Combined with pneumatic flexible glove training, mirror therapy can not only significantly improve the hand function of stroke survivors, but also activate the relevant brain regions of both hemispheres through bilateral motor patterns combined with multisensory stimulation, promoting the balance between hemispheres.

Alzheimer's disease(AD)is mainly characterised by irreversible progressive cognitive dysfunction,which is complex in its pathogenesis and difficult to cure,and seriously affects the quality of life of patients.MicroRNA(miRNA)is a type of small non-coding RNA with high targeting specificity and potential for multi-pathway regulation.This paper takes miRNA as the entry point to systematically elaborate the mechanism of action of traditional Chinese medicine intervening in AD by regulating miRNA.The results revealed that the active ingredients of traditional Chinese medicine(e.g.notoginsenoside R1,salidroside,catalpol,madecassoside,baicalin,dihydromyricetin,osthole,berberine,ursolic acid,parthenolide,thymoquinone,plumbagin),the extracts of traditional Chinese medicine(e.g.,Ganoderma extract and Ginkgo biloba leaf extract),and the compound formulas of traditional Chinese medicine(e.g.,Dihuang yinzi decoction,modified Shuyu pill,and Anshen dingzhi formula)can regulate miRNA to reduce the production and deposition of β-amyloid protein,inhibit the over-phosphorylation of τ protein,and inhibit the neuroinflammatory response and programmed neuronal death by regulating miRNA,thus playing a role in intervening in AD.

Objective:To investigate risk factors for the efficacy for appropriate medication use in elderly patients with type 2 diabetes mellitus(T2DM)and to establish a risk prediction model for the efficacy for appropriate medication use by using Logistic regression analysis and the receiver operating characteristic(ROC)curve.Methods:A total of 305 elderly patients with T2DM admitted to pharmacy department of our hospital from Jan.2018 to Aug.2018 were enrolled in this retrospective study.Of the 305 patients, 166(54.4%)were female, with a mean age of (74.9±7.2) years old, a disease course of (15.2±9.6) years and a hospital stay of (10.4±3.2) d, receiving (2.0±0.9) types of antidiabetic drugs.Patients were assessed by the Self-Efficacy for Appropriate Medication Use Scale(SEAMS), the Morisky Medication Adherence Scale-8(MMAS), the Adherence to Refills and Medications Scale(ARMS), the Charlson Comorbidity Index(CCI)and the Mini Mental State Exam(MMSE). Main biochemical indicators were recorded.The influencing factors for appropriate medication use efficacy were analyzed by Logistic regression analysis, and a risk prediction model was consequently established by the ROC curve.Results:According to SEAMS results, 233 patients(76.4%)had sufficient efficacy(≥26 points)and 72 patients(23.6%)had insufficient efficacy(<26 points). There were significant differences in parameters including age, disease course, hospital stay and fasting blood glucose(FBG)between the above two groups( P<0.05). Logistic regression analysis showed that age, FBG level and ARMS score had correlation with self-efficacy for appropriate medication use( P<0.05). ROC curves showed that the predictive efficiency of joint predictor Y [Logit(P)=-15.164+ 0.434X ARMS score-0.067X age-0.082X FBG reaching standard]was better than that of the other three single factors(AUC=0.910, 95% CI: 0.873-0.947, P<0.01)and could be used as an optimal predictor for the evaluation of self-efficacy for appropriate medication use. Conclusions:Compared with MMAS, ARMS is more suitable for medication adherence assessment in elderly T2DM patients.In clinical practice, pharmacists can provide individualized medication services through evaluating the efficacy of rational drug use and the risk prediction model, in order to elevate the ability of self-medication management and quality of life.

Radiomics and radiogenomics are used to provide comprehensive tumor biological characte-ristics and further clinical information by extracting,screening and analyzing the most valuable quantitative ra-diomics features. In recent years,numerous studies have shown that radiomics plays a role in the diagnosis, treatment and predicting efficacy and prognosis of lung cancer. Radiogenomics shows a great value in the pre-diction of lung cancer gene phenotype and individualized precision treatment by combining radiomics features with genomics,proteomics and so on. Radiomics and radiogenomics are non-invasive,quantitative,and repro-ducible,and they can provide multidirectional tumor biological characteristics,which are expected to be widely used in the precise medical treatment of lung cancer in the future.

Objective To investigate the effects of risk factors on non thyroidal Illness syndrome (NTIS) in elderly inpatients.Methods A total of 819 elderly inpatients who met inclusion criteria were consecutively recruited in thiscross-sectional study.Physicalmeasurements and mini nutritional assessment using the mini nutritional assessment-short form (MNA-SF) score were conducted.A serum levels of thyroid stimulating hormone (TSH),free triiodothyronine (FT3),free thyroxine (FT4),brain natriuretic peptide (BNP) and C-reactive protein (CRP) were examined.Data were analyzed with multivariatelogistic regression.Results The significant differences were found between NTIS group (n=145) versus control group (n=674)inage (78.5±8.1) years vs.(75.1±8.6) years(t=5.422,P＜0.01),in body mass index (23.0 ±3.8) kg/m2 vs.(24.1±3.6) kg/m2,in MNA-SF score 11.2±2.3 vs.12.3± 1.8(t=-3.315,6.754,P＜0.01),in level of serum albumin (36.0±4.5) g/L vs.(38.4±3.6) g/L (t=-6.977,P＜0.01),in triglyceride level (1.3± 0.9) mmol/L vs.(1.5±1.0) mmol/L(t=-3.039,P＜0.01),inCRP (Z=-8.857,P＜0.01)),and in BNP (t=6.331,P＜0.01).Logistic regression analysis revealed that age＞ =80 years (OR=2.433,95％CI:1.357 4.361),malnutrition (OR=1.946,95％CI:1.261-3.001),renal insufficiency (eG FR＜60 ml/min,OR =2.131,95％ CI:1.367-3.322),and high level of CRP (10 mg/L and 50 mg/L:OR=3.446,95％CI:2.117-5.611;over 50 mg/L:OR =10.029,95％CI:4.693-21.432,all P＜0.01)) were risk factors for NTIS.Conclusions Non-thyroidal illness syndrome in elderly inpatients is correlated with advanced age,renal insufficiency,malnutrition and stress,which are the independent risk factors.

Objective To explore the determinants of serum uric acid (UA) levels and the relationship between UA and cardiovascular disease in elderly patients.Methods A cross-sectional design was used.A total of 1 066 elderly patients were consecutively recruited in the study.Anthropometric measurement and lifestyle survey were performed,and serum UA,lipid profile,glucose,homocysteine (Hcy) and superoxide dismutase (SOD) were measured.The determinants of serum UA levels and correlation between UA and cardiovascular disease were analyzed by regression.Results The prevalence of hyperuricemia was 21.9％ (25.9％ in men and 18.7％ in women).Partial correlation analysis showed the level of serum UA was positively correlated with Hcy (r=0.163,P=0.000),body mass index (r=0.128,P=0.004) and triglyceride (r=0.133,P=0.003),and negatively correlated with HDL-C (r=-0.103,P=0.021).After adjustment for potential confounding factors,multivariate analysis showed eGFR (β =-2.044,t =-10.544,P =0.000),gender (β =42.065,t=4.700,P=0.000),Hcy (β=1.367,t=3.714,P=0.000),BMI (β=3.370,t=2.706,P=0.007),TG (β=14.120,t=2.589,P=0.010) and SOD (β=-0.636,t=-3.079,P=0.002) were independent determinants for UA levels in elderly patients.Logistic regression analysis indicated that mild elevation of UA levels was a risk factor of hypertension (OR=1.925,95％ CI=1.124-3.295) in women and OR=1.780 (95％ CI=1.010-3.136) in men].High UA levels increased the risk of coronary heart disease in women [OR=1.710 (95％ CI=1.157-2.526)],but decreased the risk of ischemic stroke in men [OR=0.524 (95％ CI=0.335-0.820)].Conclusions In elderly patients,serum UA levels were affected by renal function,gender,BMI and serum Hcy,TG and SOD.Mildly elevated UA levels increased the risk of hypertension.High UA levels increased the risk of coronary heart disease in women and decreased the risk of ischemic stroke in men.

Objective To investigate the change of HR,RR and arterial blood gas in the treatment of BiPAP ventilation in patients with acute pulmonary.Methods Fifty eight patients with acute pulmonary edema were randomized into two groups.The control group(n =29)were given conventional general treatment only,but treatment group(n =29)were given BiPAP ventilation besides conventional treatment.4 h later,heart rate (HR),respiratory rate(RR),SaO2,pH,PaO2 and PaCO2 were compared between the two groups.Hospitalization duration and incidence of invasive mechanical ventilation were recorded after discharge.Results Compared with pre-treatment,HR,RR,SaO2 and PaO2 in treatment group were improved significantly(HR 124 ± 12 beat/min vs 83 ±6 beat/min,t =5.372,P ＜0.01)(RR 37 ±5 beat/min vs 19 ± 8 beat/min,t =4.285,P ＜0.01)(SaO2 81.4％ ±5.4％ vs94.1％ ±4.2％,t=2.731,P＜0.05)(PaO2 53.2±5.4 mm Hg vs 89.1 ±8.5 mm Hg,t=5.763,P ＜0.O1).And these four indicators were also improved in control group after treatment,(HR 123 ± 10 beat/min vs 95 ± 8 beat/min,t =t =3.459,P ＜ 0.01)(RR 36 ± 7 beat/min vs 24 ± 6 beat/min,t =3.127,P ＜0.01)(SaO2 81.8％ ±5.7％ vs 88.3 ±4.5％％,t =2.314,P ＜0.05)(PaO2 53.5 ±4.6 mm Hg vs 72.8 ±9.5 mm Hg,t =3.756,P ＜0.01).HR,RR,SaO2 and PaO2 in treatment group were more significantly improved than that of control group(P ＜ 0.01 or P ＜ 0.05).Hospitalization duration in treatment group was significantly shorter than that of control group(9 d vs 15 d,t =3.763,P ＜ 0.01).The incidence of invasive ventilation were lower than that of control group too(but P ＞ 0.05.Conclusion These results suggested that BiPAP ventilation can regulate HR RR and blood gas value to accetable levels,shorten hoptipitalization duration and reduce the incidence of invasive ventilation.It is proved to be an effective therapeutic technique in the treatment of acute pulmonary edema patients.

Objective To explore the role of T cell-mediated immunity in the pathogenesis of venous thromboembolism ( VTE ) by analyzing the differential expression of T cell immune-related gene mRNAs peripheral blood mononuclear cells (PBMCs) between VTE patients and controls with GeneChip Human Genome. Methods Human eDNA microarray analysis was employed in PBMCs from 20 VTE patients and 20 hypertensive controls,and random variant model (RVM) corrected t-test was used for statistical analysis of differential gene expression.Results Six mRNA stripes including CD247,CD3D,CD3G,Granzyme A (GzmA),Granzyme B (GzmB) and Zeta-chain-associated protein kinase 70 (ZAP70)were found to be associated with T cell-mediated immunity.Significant down-regulation of these six mRNAs was found in the VTE group compared with the controls ( 15.3050 ± 0.6346 vs 15.8053 ± 0.5567,13.7878 ±0.7731 vs 14.3820 ±0.4857,13.3299 ± 0.9104 vs 14.1246 ± 0.6011,14.8893 ± 0.8675 vs 15.5305 ±0.4624,15.9113 ±0.8123 vs 16.4553 ±0.5055,14.3652 ±0.7717 vs 14.3652 ±0.7717;all P values ＜ 0.05 ).Conclusions T cells' function including antigen recognition,signal transduction and cytotoxicity was impaired in VTE patients.T cell-mediated immunity dysfunction probably plays an important role in the pathogenesis of VTE.
