Extranodal natural killer (NK)/T-cell lymphoma, nasal type (ENKTL) is an aggressive non-Hodgkin lymphoma and there are no standard treatment options for ENKTL. For localized patients, radiotherapy alone or radiotherapy combined with chemotherapy could be took into consideration. Systemic combination chemotherapy remains the primary treatment for patients with advanced ENKTL. The efficacy of anthracycline based conventional chemotherapy in ENKTL is unfavorable. This paper reviews the treatment progress of ENKTL in recent years.

Angiotensin-converting enzyme 2 (ACE2)-angiotensin (1-7) [Ang (1-7)]-Mas constitutes the vasoprotective axis and is demon-strated to antagonize the vascular pathophysiological effects of the classical renin -angiotensin system .We hypothesize that upregulation of ACE2-Ang (1-7) signaling protects endothelial function through reducing oxidative stress , thus resulting in beneficial outcome in di-abetes.Ex vivo treatment with Ang (1-7) augmented endothelium-dependent relaxation (EDR) in renal arteries from diabetic patients . Both Ang (1-7) infusion via osmotic pump (500 ng? kg -1? min-1 ) for 2 weeks and exogenous ACE 2 overexpression mediated by ad-enoviral ACE2 via tail vein injection rescued the impaired EDR and flow-mediated dilatation ( FMD) in db/db mice.Diminazene acetu-rate treatment (15 mg? kg-1? d-1 ) activated ACE2, increased the circulating Ang (1-7) level, and augmented EDR and FMD in db/db mouse arteries.In addition, activation of the ACE2-Ang (1-7) axis reduced reactive oxygen species (ROS) overproduction de-termined by dihydroethidium staining , CM-H2DCFDA fluorescence imaging , and chemiluminescence assay in db/db mouse aortas and also in high-glucose-treated endothelial cells .Pharmacological benefits of ACE 2-Ang ( 1-7 ) upregulation on endothelial function were confirmed in ACE2 knockout mice both ex vivo and in vitro.We elucidate that the ACE2-Ang (1-7)-Mas axis serves as an important signal pathway in endothelial cell protection in diabetic mice , especially in diabetic human arteries .In summary, endogenous ACE2-Ang (1-7) activation or ACE2 overexpression preserves endothelial function in diabetic mice through increasing nitric oxide bioavail -ability and inhibiting oxidative stress , suggesting the therapeutic potential of ACE 2-Ang(1-7) axis activation against diabetic vasculop-athy.

Relations between doctor and patient are basic and important human relation in medical practice.Because of some reasons,the relations appear tense status in our country,moreover the market economy flourishingly develops,as the result of medical organizations suffering more and more existent pressure.It is an important subject faced for people,especially for medical worker,to righly think the existed defects,and set up the mutual action between doctor and patient.

In the treatment of 169 cases of the patients sick with intervertebral disc hemiation by integrated application of acupuncture therapy,Chinese massage therapy and herbal fumigation method.the results showed cure in 129 cases.improvement in 33 cases and failure in 7 cases,and the total effective rate was 95.9%.

Aim To observe effects of compound dialysate of Chinese herbs and Western medicines on small intestinal mucosa ultrafiltrative function in dogs. Methods Twenty Beagle dogs were divided into 4 groups: NS, control (CG), lower ligustrazine dose (LLDG) and higher ligustrazine dose group (HLDG). According to the arteriovenous region of small intestine mesentery to make three isolation loops for comparative study, they were respectively jejunum loop (JL), jejunoileum loop (JIL) and ileum loop(IL), and input hypersonic sample solution through vein after blocking the renal arteries to make the man-made renal failure models such as electrolytic disorder, azotemia etc. Meanwhile, the dialysate was perfused from the inlet of these isolation loops, respectively.Finally, these secretion of small intestine loops and blood samples which arteria and venae of the small intestine mesentery every 30 minutes were collected to determine the density of K+, Na+, Cl-, UN, CR, UA and the clearance and filtration rate in each group were calculated. Results The clearance rate and filtration rate in LLDG were remarkablely higher than that in the LHDG、the CG and the NS (P

Objective To evaluate the effect of octreotide on the survival of patients with advanced hepatocellular carcinoma(HCC).Methods Electronic databases searches were conducted.Meta-analysis of all randomized controlled trials (RCTs) comparing octreotide versus placebo or no treatment was performed.Results Five RCTs including 579 patients with HCC wers assessed.Meta-analysis of the five studies showed that octreotide had no significant effect on the 6,12 and 24 months survival rates of the patients(6months:OR=1.69,95%CI 0.89-3.21,P=0.11;12 months:OR=2.41,95%CI 0.83-6.93,P=0.10;24months:OR=0.58,95%CI 0.28-1.17,P=0.13).To perform the sensitivity analysis,the blank study,the trial detecting somatostatin receptor expression,the study with short survival or the two trials with short follow-up intervals were excluded,and the results also showed that the octreotide treatment had no significant effect on the 6 and 12 months survival rates.A sensitivity analysis based on two trials indicated that the 24months survival rate of the octreotide group was even lower than that of the control group(OR=0.51,95% CI0.27-0.98,P=0.04).Conclusions This Meta-analysis demonstrates that octreotide could not improve the survival of patients with advanced HCC.The administration of octreotide should not be recommended for the treatment of advaneed HCC.

Objective To investigate the clinical value of ABCD score combined widl diffuse weighing imaging(DWI)for the estimation of transient ischemic attack(TIA)advancing to cerebral infarction in 7 days.Method The clinical dataincludingABCD score and DWI of 105 cases with TIA were analyzed.Results None of TIA patients with ABCD scores＜3 advanced to cerebral infarction.There were 83 cases with ABCD scores≥3,among whom 24 cases(28.9%)advanced to cerebral infarction.The higher ABCD scores,the higher incidence of cerebral infarction(P＜0.01).Nine of 42 cases(21-4%)with DWI abnrmal advanced to cerebral infarction,while 2 of 50 cases(4.0%)with normal DWI advanced to cerebml infarction (P＜0.05).Conclusion ABCD score is alleffective method for the estimation of TIA advancing to cerebral infarction,and when combined with DWI it is more efficient
