Objectives To analyze the characteristics of serum protein electrophoresis(SPE)in chronic heart failure(CHF) patients,evaluate prognostic value and explore the reason of it preliminarily.Methods Retrospective exploration of 6 1 8 chronic heart failure patients in study cohort (CHF cohort)and 70 patients with normal cardiac function in control cohort was made to comp are the difference of serum protein electrophoresis.Then,CHF Patients were tracked down by phone to discuss the correlation between adverse event rate (re-hospitalization rate or mortality rate)and their SPE.Last,the multiple linear regression analysis of SPE and biochemical indicators was made to explore the reason of the abnormality.Results Pa-tients of CHF cohort appeared to have significantly rising beta 1-gobulin(6.01±1.06)%,compared with control cohort(t=3.417,P<0.001).Post-discharge adverse event rate displayed by the curve demonstrated that patients with beta 1-gobulin higher than or equal to 6% had much more adverse event rate than those with beta 1-gobulin less than 6%,in 7 to 24 months after discharged from the hospital,which had been proved by the Chi-square test of 0.031(P<0.05).Multiple linear regres-sion analysis showed that beta 1-globulin and serum creatinine,uric acid,and sodium were significantly correlated.Conclusion CHF patients had higher beta 1-gobulin of SPE probably because of immunoactivation,which may increase their re-hospi-talization rate ormortality rate after hospital discharge.Meanwhile,growing beta 1-gobulin is closely correlated with blood creatinine,uric acid and blood natrium and becomesa risk of kidney dysfunction due to hypoperfusion and accumulation of se-rum immunoglobulin.

Objective To observe the efficacy and safety of albumin bound paclitaxel in the treatment of retreatment advanced non-small-cell lung cancer (NSCLC).Methods Retreatment NSCLC patients failed from first line regimen or beyond were treated with albumin bound paclitaxel weekly by intravenous dose of 130 mg/m2 on day 1 and day 8,with a 21-day cycle.Efficacy was evaluated every two cycles and side effects were observed during each cycle.Results None of 69 patients achieved complete remission (CR),15 patients (21.7 ％) achieved partial remission (PR),and 23 patients (33.4 ％) achieved stable disease (SD).Objective response rate (ORR) was 21.7 ％,disease control rate (DCR) was 55.1％,and progress free survival (PFS) time was 3.8 months.Efficacy was not correlated with gender,age,histology and lines of previous treatment (all P ＞ 0.05).Main adverse reactions included neutropenia,alopccia and neurotoxicity,which were all tolerable.Conclusion Weekly albumin bound paclitaxel is effective and well tolerated in the treatment of retreatment advanced NSCLC,which can be considered as the second line or beyond regimen.

Objective:To determine the prevalence of sarcopenia and explore related influencing factors of sarcopenia in maintenance hemodialysis (MHD) patients.Methods:MHD patients aged ≥18 years old and receiving therapies of ≥3 months from March 2019 to December 2019 in Blood Purification Centre of Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine were retrospectively enrolled in this study. General data of the patients were collected. Grip strength was measured by the Jamar dynamometer and the chair stand was measured by a chair of standard height to assess skeletal muscle strength and appendicular skeletal muscle mass was measured by dual energy X-ray absorptiometry. Baseline data between MHD patients with and without myasthenia were compared. Logistic regression analysis method was used to analyze the influencing factors for sarcopenia in MHD patients.Results:A total of 125 MHD patients were enrolled, with 68 males (54.4%), age of (59.4±14.9) years and median dialysis age of 51.0(23.5, 101.0) months. Sarcopenia was diagnosed in 39 cases (31.2%). Compared with MHD patients without sarcopenia, age, tumor necrosis factor-α, von Willebrand factor (vWF) and proportion of using α ketones were higher, and serum carbondioxide combining power (CO 2CP), prealbumin, albumin and proportion of regular exercise were lower in MHD patients with sarcopenia (all P<0.05). Multivariable logistic regression analysis results showed that low CO 2CP ( OR=0.717, 95% CI 0.576-0.892, P=0.003), high vWF ( OR=1.037, 95% CI 1.016-1.058, P<0.001) and no regular exercise ( OR=0.309, 95% CI 0.118-0.810, P=0.017) were independent influencing factors of sarcopenia in MHD patients. Conclusions:The prevalence of sarcopenia in MHD patients is high. Low CO 2CP, high vWF and no regular exercise are independent influencing factors for sarcopenia in MHD patients.

Objective Intradialytic hypotension (IDH) is one of the common complications during hemodialysis,however its diagnostic criteria are highly controversial at present.In order to fully understand the prevalence of IDH in our center and figure out which diagnostic criteria is better for Chinese maintenance hemodialysis (MHD) patients,we choose several IDH definitions by reviewing published literatures and analyze their association with mortality.Methods The patients were recruited from Blood Purification Center of Ruijin Hospital undergoing hemodialysis during July 2012.Pre-,intra-and post-dialysis blood pressure were recorded.Patients' clinical characteristics,laboratory results and cardiac ultrasound results were collected.Based on several IDH definitions,we investigated the prevalence rate of IDH and its frequency among MHD patients.SPSS 23.0 was used to analyze data and conduct survival analysis.Results Totally 219 MHD patients underwent 16084 hemodialysis in 6 months.The prevalence rate,overall and individual frequency of IDH fluctuated between 45.21％-100.00％,4.64％-37.60％ and 0.00％-33.00％ respectively.For every IDH criteria,the patients were recruited into the group IDH(+) if they ever met the corresponding definition,otherwise the group IDH(-).Survival analysis found that IDH (the criteria of an absolute systolic blood pressure (SBP) ＜ 90 mmHg or with a decrease of SBP≥ 20 mmHg) could decrease the risk of patients' cardiovascular mortality but was not relevant to all-cause mortality.Further analysis showed these patients had better cardiac functions mainly reflecting in lower Pro-BNP (2880 ng/L vs 6909 ng/L),lower prevalence rate of left ventricular hypertrophy (52％ vs 83％) and higher left ventricular ejection fraction (65.0％ vs 62.5％) than IDH(-) patients.No correlation was found between other IDH criteria and mortality.Conclusions The prevalence rate,overall and individual IDH frequency of IDH are of high variability when diagnosed by different IDH criteria.All IDH episodes defined by our selected definitions are of no association with all-cause mortality.An absolute SBP ＜ 90 mmHg or with a decrease of SBP≥20 mmHg can decrease the risk of cardiovascular mortality due to their better cardiac function.Large scale researches should be conducted to find optimal IDH definition and explore the association of IDH and mortality.

Objective To prepare scutellarin liposomes and to investigate the pharmacokinetics in rats. Methods The liposomes of scutellarin coated with carbopol were prepared with the film dispersion method.Minicolumn centrifugation method was applied to measure the encapsulation efficiency (EE) before and after coating. SD rats were randomly divided into three groups, which were given intragastric administration of scutellarin suspension, scutellarin liposomes, and carbopol-coated scutellarin liposomes, respectively. And then the pharmacokinetic parameters were compared. Results Carbopol-coated scutellarin liposomes after intragastric administration in rats showed pharmacokinetic characteristics of two-compartment model. The main pharmacokinetic parameters of scutellarin suspension,scutellarin liposomes,and carbopol-coated scutellarin liposomes were as follows:AUC0-∞(50.03±13.45) μg?h?mL-1 ,(78.99±20.28) μg?h?mL-1 ,and (107.97±27.26) μg?h?mL-1 , respectively. Conclusion After coated liposomes, the oral bioavailability of scutellarin 1iposomes can be significantly improved,and the maximum drug concentration also increased.

[Objective]To investigate the therapeutic effect and molecular mechanism of Chinese medicine Saffron on Parkinson's disease(PD)based on network pharmacology and molecular docking.[Methods]The pharmacodynamic components of Saffron included in the analysis were determined through the pharmacological database and literature research of the Chinese medicine system.With the help of compound target database and disease target database,the corresponding targets of saffron components and PD targets were predicted,respectively.Enrichment analysis of compound-disease intersection targets was made by using R procedures and referencing correlated R-packages.Construction of protein-protein interaction(PPI)networks and analysis of node-related topological parameters.Simulate molecular docking to verify binding properties of representative compounds and key targets.The pharmacodynamic properties of Saffron acid on key targets were preliminarily evaluated by experiments.[Results]The 8 components of saffron with druggable potential corresponded to 279 targets,PD had 2 183 disease targets,and a total of 98 intersection targets of compounds and diseases were obtained.Enrichment analysis showed that the compound-disease intersection target was involved in biological processes such as reactive oxygen radical synthesis and metabolism,neuroinflammation and mitogen-activated protein kinase(MAPK)signaling pathway.The key targets identified by PPI network analysis were tumor necrosis factor(TNF)and signal transducer and activator of transcription 3(STAT3).Molecular docking showed that saffron glycosides and saffron acids had stronger binding activity with TNF.Experiments had shown that saffron acid can reduce the transcription levels of lipopolysaccharide-induced cytoinflammatory factor TNF,interleukin-1β(IL-1β)and inducible nitric oxide oxide synthase(iNOS).[Conclusion]Saffron can be used as a candidate for PD treatment,and its neuroprotective effect may involve the interaction and synergy of many targets and signaling pathways,which deserves special attention to the activity of saffron acid against central nervous system inflammation.
