The modest pressure promotes the graduate to keep continuous energy and focus on scientific research,but too much pressure will lead to mental problem and serious moral shortcoming.Reformation of scientific evaluating and promoting system,enhancement of scientific interest and reconstruction of mental training system should be the important ways to release the pressure of scientific research of the graduate.

This study tried to investigate the change in the glomerular filtration rate in initiation of a low-protein diet (LPD) in the elderly patients with diabetic nephropathy, and to elucidate whether this initial phenomenon is reversible or irreversible. 24 non-insulin-dependent diabetic patients with renal failure patients were randomized to LPDⅠgroup (0.6g *kg-1*24h-1), LPDⅡgroup (0.8g*kg-1*24h-1), and NPD group for four weeks (phaseⅠ). Between weeks 4 and 8, all patients received NPS (phaseⅡ). Dietary protein intake (g*kg-1*24h-1), SCr, Ccr, albuminuria excretion rate and arterial blood pressure were measured at baseline and after four- and eight-weeks of follow-up, respectively. During phaseⅠ, a significant decline in dietary protein intake, Ccr, Scr, and albuminuria excretion rate were observed in the LPDⅠgroup and LPDⅡgroup. There was not any change in the NPD group. Conversely, during phase Ⅱ, with a significant increase in dietary protein intake, Ccr, Scr and albuminuria excretion rate increased in LPDⅠ group and LPD Ⅱ group compared with the NPD group. It suggested that dietary protein restriction for four weeks induces a reversible decline in GFR, Scr and albuminuria excretion rate in noinsulin-dependent diabetic nephropathy patients with renal failure, whereas systemic blood pressure remains unchanged.

Liraglutide is a long-acting human GLP-1 analogue,which provides pharmacological level of GLP-1 and combines with GLP-1 receptor widely distributing in the body.Liraglutide demonstrates multiple antidiabetic and other effects,including glucose-dependent glucose-lowering action,pancreatic islet cells protection,gastric emptying inhibition,appetite reduction/feelings of satiety and fullness increasing,weight loss,cardioprotection and blood pressure lowering action.Meanwhile,clinical practice also shows that some gastrointestinal adverse events occur accompanying with good glucose control and weight loss.This review will explain the potential mechanisms of GLP-1 and gastrointestinal reaction,clinical evidence of liraglutide and effective management rules,aim to help readers better understand this issue,as well as to advise clinicians of proper use of liraglutide while reducing or avoiding those adverse events.

Objective To investigate the anti-HBV mechanism of oxymatrine in vitro.Methods The antiviral mechanism of oxymatrine was analyzed through detecting the expression and function of TLR9 signal pathway and the secretion of antiviral cytokines from PBMCs treated by oxymatrine in vitro.Results Oxymatrine could not only induce IFN-α and IFN-γ secretions from PBMCs directly, but also effectively augmented the expressions of TLR9, MyD88 and TRAF6 at mRNA level, and activated the TLR9 signal transduction pathway. TLR9 ligand could induce IFN-α, IFN-γ and TNF-α secretion a lot from PBMCs pretreated by oxymatrine.Conclusion Oxymatrine possesses an anti-HBV activity via activation of TLR9 signal pathway and secretion of antiviral cytokines.

ObjectiveTo evaluate the efficacy and safety of ibutilide for conversion of paroxysmal and persistent atrial fibrillation.Methods31 patients with atrial fibrillation duration less than 90 days were included into amiodrone or ibutilide group.16 patients were intravenously administer with amiodrone and 15 patients with ibutilide separately.Conversion rate,time needed to converse and adverse effects were compared between two groups.ResultsThe total conversion rate of ibutilide group was significantly higher than that of amiodrone group (66.7％ vs 37.5％,x2 =1.98,P ＜ 0.05 ).Time needed to converse was significantly shortened in ibutilide group compared with amiodrone group [ ( 31.75 ± 7.39 ) min vs ( 51.87 ± 9.26 ) min,t =3.67,P ＜ 0.05 ].No clinical significant adverse effects were observed in ibutilide group.ConclusionIntravenous administration of ibutilide in cardioversion of paroxysmal and persistent atrial fibrillation was more safe and effective than amiodrone.

Allogeneic hematopoietie stem cell transplantation(alloHSCT) is a potentially curative therapy for patients with hematological malignant disease, autoimmune disease or hereditary disease.However, graftversus-host disease (GVHD), which is one of the most serious complications, influences the prognosis of alloHSCT. Mechanisms of GVHD is so complicated that there is still no perfect way to treat the patients at present. Recently, mesenchymal stem cells(MSC) become new hotspots because of their immunomodulatory properties and potential to suppress alloreactive T cell responses.Animal experiments showed that MSC were effective during the prevention and treatment of GVHD. This paper is to summarize the acting mechanism of MSC' effect on the prevention and treatment of GVHD after alloHSCT.

Objective To explore the influencing factors of hypertensive cerebral hemorrhage in 68 patients with supratentorial prognosis of recovery of neurological function.Methods Clinical data of 68 patients with high blood pressure treatment supratentorial intracerebral hemorrhage,and brain CT,laboratory data were retrospectively analyzed.Neurological functions and related indicators change of were daalyzed by univariate and multivariate Logistic regression analysis.Results Gender,systolic blood pressure,diastolic blood pressure,red blood cell count,such as the impact on the prognosis was not statistically significant(all P ＞ 0.05) ; median line offset,nosocomial infections,surgery,gastrointestinal bleeding,heart failure,treatment Barthel index(BI) were a significant influence on the prognosis (all P ＜ 0.01).The median line offset,nosocomial infections,bleeding,gastrointestinal bleeding,heart failure,BI integration were the main factors affecting the prognosis of neurological function recovery.Conclusion The factors which affects nerve function recovery is an important part of improving neurological outcomes.We should emphasize them.

Objective To compare the effects of early and conventional instillation of normuscle invasive bladder cancer after transurethral resection of bladder tumor.Methods The clinical data of 32 patients with normuscle invasive bladder cancer were retrospectively analyzed.They were divided into observation group (16 cases) and control group (16 cases).The clinical effects of the two groups were compared.Results The recurrence rate of two groups was significantly different (x2 =3.864,P ＜ 0.05).The average recurrence time of two groups was significantly different (t =6.389,P ＜ 0.05).The incidence rate of adverse reactions (x2 =0.369,P ＞ 0.05) and the incidence rate of toxic reactions(x2 =2.222,P ＞ 0.05) in two groups had no statistically significant differences.Conclusion It can lower the recurrence rate for early and conventional instillation of normuscle invasive bladder cancer after transurethral resection of bladder tumor and to delay the recurrence time,so it is widely applicable for clinic cure.

Lung cancer-related papers published by authors of China were retrieved from PubMed and the high frequency subject headings and subheadings were extracted from them using the Bicomb system.The status quo and hot spots of lung cancer-related studies in China were analyzed .

Objective To investigate the damage of mice liver and kidney with the compatibility application of Paeoniae radix rubra and Veratrum nigrum, and explore its mechanism. Methods We examined the alanine aminotransferase, aspartate aminotransferase (AST), lactic dehydrogenase, creatinine and urea nitrogen from serum, and glutathion peroxidase (GSH-Px) and malondialdehyde (MDA) from liver and kidney tissue after intragastric administration of different ratio (4∶1, 2∶1, 1∶1, 1∶2, 1∶4) of Paeoniae radix rubra and Veratrum nigrum in mice for 22 d. Results Paeoniae radix rubra used with Veratrum nigrum did not induce the obvious damage to liver with AST increase, but induced the obvious damage to kidney. At the same time, the depressed GSH-Px activity and the increased MDA content were observed in kidney tissue. When Paeoniae radix rubra and Veratrum nigrum is on a ratio of 2∶1, the kidney injury was the most obvious. Conclusion Paeoniae radix rubra used with Veratrum nigrum in varying proportions could induce the kidney injury in mice which is related to the oxidation-antioxidation balance disturbance.
