The nitric oxide donor drugs have the functions of anti-hyperplasia, inhibiting platelet adhesion and aggregation, regulating immune response, etc. It suggests that these drugs play important roles in therapy of cardiovascular diseases, male impotence and pregnancy-induced hypertension syndrome.

Resveratrol,which is produced by natural plants,has various biological activities,including anti-inflammatory,antioxidant and anticancer properties.Recently,it is found that resveratrol can inhibit the proliferation and promote the apoptosis of breast cancer through multiple molecular targets,which provides a theoretical basis for resveratrol used in the treatment of breast cancer.

Objective To study the changes of liver function and its clinical significance during the treatment of hepatocellular carcinoma by hepatic arterial and segmental arterial embolization. Methods Hepatic arterial embolization (conventional LP-TAE) was performed in 52 cases of hepatocellular carcinoma and segmental arterial embolizational(segmental LP-TAE) was done in 33 cases. The main data of the change of liver function were reviewed in three days and six months after treatment. All cases were followed up for 1 to 5 years. Results The change of ALT, AST, ALP, TBIL in conventional LP-TAE were remarkably increased than that in segmental LP-TAE after three days (P=0.000). After six months by LP-TAE, the Child of liver function in segmental group decreased obviously lighter than that in conventional group (P=0.000). The survival rates at 1-, 3-, and 5-year were 90.9%, 60.6% and 30.3% in segmental LP-TAE, respectively, and 61.5%, 21.2% and 7.7%, in conventional LP-TAE, respectively (P =0.003, P =0.000, P =0.006). Conclusion Segmental LP-TAE possesses stronger anticancerous effect and much less damage to liver function. Segmental LP-TAE is obviously superior than conventional LP-TAE in long term effectiveness.

Objective To investigate the clinical significance of dynamic change of serum IL‐17A/IL‐23 in131 I treatment of Graves hyperthyroidism by dynamically detecting the serum IL‐23/Th17 axis related factor levels before and after 131 I treatment of Graves hyperthyroidism .Methods 30 untreated inpatients with Graves disease(GD) in our hospital were selected as the T0 group , those treated by 1- ,3- ,6-month 131 I treatment were taken as the group T1 ,T3 and T6 .Contemporeneous 30 individuals under‐going healthy physical examination were selected as the normal control (NC) group .The various groups had no statistical differences in the aspects of the age ,gender and disease course ,and had the comparability (P>0 .05) .Serum concentration of IL‐17A and IL‐23 was measured by the enzyme‐linked immunosorbent assay (ELISA) technique .FT3 ,FT4 and TSH were detected by combing with clinic .Results The levels of serum IL‐17A and IL‐23 before131I treatment were significantly higher than those in the NC group(P<0 .05);with the treatment proceeding ,which at ,1 ,3 ,6 months were gradually decreased ,the differences were statistically signifi‐cant but(P<0 .05);after 6 -month 131 I treatment in the GD patients ,the effects of IL‐17A and IL‐23 double negative in the T6 group were better than those of single negative ,and better than those of double positive ,the differences were statistically (Fisher value=13 .273 ,P<0 .05) .Conclusion Dynamically monitoring the serum IL‐23/Th17 axis related factor levels has the significance for guiding treatment ,judging the curative effect and predicting recurrence .

Objective To investigate the effects of irbesartan hydrochlorothiazide combined with candesartan cilexetil in the treatment of elderly patients with hypertension and its protective effect on cardiac function.Methods 180 elderly patients with hypertension were selected,and they were randomly divided into observation group and control group according to the digital table,90 cases in each group.The observation group was given irbesartan hydrochlorothiazide combined with candesartan treatment,the control group was given candesartan.The heart function improvement after treatment,clinical efficacy and patients in hospitalization,complications,critical events and new death of the two groups were compared.Results After treatment,the heart rate,EVDD,SBP and other indicators of the two groups declined,which of the observation group[(56.14 ± 6.15)mm,(112.12 ± 20.12)mmHg,(70.45 ± 8.69/min)]were lower than the control group[(60.12 ± 6.78) mm(119.45 ± 21.45) mmHg,(82.12 ± 9.12/ min)],there were significant differences between the two groups (t1 =4.124,P =0.000;t2 =2.364,P =0.019;t3 =8.788,P =0.000).The total effective rate of the observation group was 93.33％,which was higher than 74.44％ of the control group,there was significant difference between the two groups (x2 =11.879,P =0.000).Conclusion Irbesartan hydrochlorothiazide combined with candesartan in the treatment of elderly hypertensive patients can effectively improve the heart function of patients,has significant effect.

Objective A two step polymerase chain reaction (PCR) strategy was used to amplify copy DNAs corresponding to the special region of the T cell receptor (TCR) ? chain. Methods and Results With this technique, a dominant TCR gene rearrangement that used the ?8 variable region gene segment was identified in a patient with cuteneous T cell lymphoma and its sequence determined from multiple independently generated subclonal PCR products. An oligonucleotide corresponding to the highly variable junctional region of the clonally expanded TCR gene rearrangement was synthesized and used for further confirming studies. Finally, from the sequence data obtained, a peptide corresponding to the ? chain junctional region sequence of the patient′s clonally expanded T cells was generated. Conclusion Preliminary studies using this peptide indicate that it is antigenic and may potentially be useful in developing a patient specific tumour vaccine.

Objective To study the classification, its incidence and some related factors of neurological complications after liver transplantation.Methods 166 cases of orthotopic liver transplantation were retrospectively studied. The classification and the incidence of the neurological complications were analyzed. In addition, the patients were divided into two groups, according to whether they suffered from neurological complications or not, to study the difference of related factors, which included gender, age, primary disease, type of operation procedure, operation time, non-hepatic time, ischemia time of donor liver, blood loss, blood infusion and immunosuppressive regimen.Results Neurological complications occurred in 28 cases (32 times), which included encephalopathy, seizure, stroke, infection of central nervous system, serious para-pyramidal syndrome and peripheral neuropathy. The total incidence was 16.9 %. Between the neurological complication group and non-neurological-complication group, no difference was found in gender, age, type of operation procedure, operation time, non-hepatic time, ischemia time of donor liver, blood loss, blood infusion and immunosuppressive regimen, but the neurological complications were closely related with primary diseases. The incidence of neurological complications was 30 % in acute liver failure, followed by post-hepatitis B liver cirrhosis (21 %), primary liver carcinoma (17.8 %), Wilson disease (16.7 %) and primary biliary liver cirrhosis (12.5 %). Interestingly as a sole complication disease, the incidence of encephalopathy in acute liver failure was 15 %, that was much higher than that in other primary disease. So was the peripheral neuropathy, which was 10 % in primary liver carcinoma.Conclusions The neurological complication is a kind of serious disease with high incidence after liver transplantation. Its onset may have some relationships with the primary liver disease.
