Objective To evaluate the effects of preoperative regional artery chemotherapy (PRACT) on gastric carcinoma. Methods Celiac arteriography was performed by transfemoral artery catheter according to Seldinger's method and superselective catheterization proceeded to the supplying artery of focus of lesion. Antineoplastic agents of Fluorodeoxyuridine (FUDR)(0.8 g/m 2), epirubicin(40 mg/m 2), oxaliplatin(80 mg/m 2) were infused into regional artery by a single administration. The specimens from 14 cases of gastric carcinoma(GC) who received PRACT were separated into pre operation group and post operation group. Both microscopic study to observe the necrosis of cancer cell and TUNEL(TdT mediated dUTP nick end labeling) method to detect the state of apoptosis were performed respectively in the two groups. Correlation of apoptosis index (AI) between the two groups, as well as correlation between the situation of necrotic tumor cell and the blood vessel, was analyzed. Results The severity of the necrosis of tumor cell was significantly higher in the PRACT group than that in the untreated group ( P

In patients with a functional gut,enteral nutrition is the preferred route of nutrition support.The favorable effects of enteral nutrition include prevention of mucosal atrophy,maintaining of the integrity of gut flora,and improvement of immunocompetence.The guidlines recommend EN be withheld in patients requiring significant hemodynamic support,because of highdose catecholamine agents which could reduce EN tolerance.Splanchnic perfusion is reduced in sepsis shock,yet vasoactive agents have demonstrated both improved and diminished perfusion.Inadequate perfusion increases the risk of experiencing rare but serious adverse events.This study summarizes the tolerability and safety of enteral nutritionin in critically iH patients with hemodynamic instability and provides theoretical basis for the early administration of EN.

Nanotechnology has shown broad application prospects in the diagnosis and treatment of cancer. Currently, nearly 80 cancer nanomedicines are under clinical investigation, and many have been approved with enhanced anti-tumor efficacy and decreased side effects. However, the presence of various barriers in related basic research, process control and clinical trials lead to extremely low translation rate. From the perspective of clinical commercialization, we summarized the progress, clinical status, challenges and opportunities of cancer nanomedicine, and presented a cutting-edge prospect on the rational design of nanomedicine and clinical trial strategies.

ObjectiveTo analyze the relationship between the patients' psychological factors and esthetics satisfaction of all-ceramic restoration of anterior teeth.MethodsThe N scales of Eysenck personality questionnaires (EPQ) were filled at the first visit,and the total scores of N scales were calculated.After restorative treatments,the satisfaction questionnaire was used to evaluate the patients' aesthetic satisfaction on material quality,color,geometry,profile,self-confidence,etc,and to analyze the relation between psychological factors and satisfaction of the patients.ResultsThe scores of EPQ N scale of the patients in this study were as follows:Nmax=23,Nmin =3,Navg =9.35±5.714.The patients had high satisfaction with restoration.Aesthetic satisfaction,color and self-confidence were in relation to the N scales scores,satisfaction of color was in relation to sickness suspicion,satisfaction of profile was in relation to enthrallment extent and guilty consciousness,and satisfaction of self-confidence improvement was in relation to anxiety and self-determination.Conclusions The psychologic factor of the patients has some influence on the esthetics satisfaction of all-ceramic restoration of anterior teeth.

Objective To investigate the effect of different sedation depth of anesthesia the BIS settings (BISis 45 and 55) to perioperative hemodynamic. Methods Thirty-two patients were randomly divided into two groups. Through closed-loop target controlled infusion technology, depth of sedation anesthesia in A:the BIS=45, and in B: the BIS=55.12 time points(i.e. before operation, tracheal intubation instant, operation beginning, 20, 40,60,80,100 and 120 minutes after operation beginning, operation accomplishment point, tracheal catheter pulling out point, before patient′s carried out of operation room)perioperativenoninvasivemean arterial blood pressureandheart rate wererecorded. Results Themean arterial blood pressurebetween the two groups at time point T2,T11 was significantly different. Within group B,compared with T1, there wassignificantdifferenceat T2,T11. Heart ratein group B at T5and T10increasedsignificantly compared with A.Within group B,heart rate at T5,T6 increased significantly compared with that at T1. Conclusion Compared with BIS 55, the sedation anesthesia depth of BIS 45 can better keep stable of blood pressureandheart rate.

Objective To investigate the effect ofglycesylated hemoglobin(GHbA,c) on tissue-type plasminngen activator (t-PA)and level of serum plasminogen activator inhibitor-1 (PAI-1) in patients with early diabetic nephropathy (DN).MethodNinety patients with early DN from April 2004 to May 2005 were divided into 3 groups according to the level of GHbA1c,which was respectively less than 7% (group A),between 7% and 9% (group B),and more than 9% (greup C).Thirty healthy adults were chosen as control group.The levels of serum GHbA1c,t-PA and PAI-1 were detected on empty stomach in the morning.Results The level of serum t-PA was lower,the activity of PAI-1 was higher in groups of DN than those in control group (P＜0.05 or＜0.01),and those were changed with the level of GHbA,c.There were significant differences between group C and group A[t-PA:(0.14± 0.06),(0.28± 0.11) U/ml; PAI-1 (3.25 ±1.01),(1.90q± 1.09) U/ml](P＜0.05).Conclusions The fibrinolytic system exists unbalance in patients with early DN.Continuous hyperglycemia in patients with early DN make unbalanced fibrinolytic system more serious.Controlling the level of GHbA1c strictly can play an important role in delaying DN progress.

Objective: Owing to fibrinogen dosage, this study is to develop a method for the bioassay of anti-gel bioactivity of Chuanxiong Rhizoma in vitro, and evaluate the antithrombotic effect of Chuanxiong Rhizoma and its related Chinese patent medicines. Methods: Chuanxiong Rhizoma powder was extracted in ethanol and water, respectively. The mixed extract was used as sample to quantify the level of fibrinogen when the stable fibrin gel was formed in vitro. The fibrinogen dosage was chosen as biomarker for anti-gel bioactivity. Sodium ferulate was chosen as reference. The anti-gel bioactivity of Chuanxiong Rhizoma was calculated according to the direct measurement belong to the bioassay statistical method in the Chinese Pharmacopoeia 2015 (Vol. 4). Moreover, the amounts of anti-gel bioactivity were quantified in nine Chuanxiong Rhizoma samples including Chuanxiong Rhizoma raw materials, decoction pieces, and related Chinese patent medicines to evaluate the applicability for this developed method. Results: Both sodium ferulate and the extract of Chuanxiong Rhizoma showed significant anti-gel bioactivity (P < 0.01). The RSD for the amounts of anti-gel bioactivity was 4.00% (n = 6) in six replicated tests with the confidence limit rate of 7.82% (n = 6). The amounts of anti-gel bioactivity were significant difference among the various types of Chuanxiong Rhizoma samples, i.e. 0.72-1.14 U/g for five Chuanxiong Rhizoma raw materials, 0.68 and 1.32 U/g for Chuanxiong Rhizoma decoction pieces and processed slice with yellow wine, 2.56 and 2.51 U/g for Tongmai Granules and Xuefu Zhuyu Tablets. Conclusion: The developed method can accurately quantify the level of anti-gel bioactivity in Chuanxiong Rhizoma raw materials, decoction pieces and related Chinese patent medicines to assess their antithrombotic effect.
