Objective To investigate the regulatory effect of TNF ? on the expression of plasminogen activator inhibitor 2(PAI 2) and its biological significance. Methods Using immunocytochemistry(ICC), terminal deoxynucleotidyl transferase mediated end labeling (TUNEL) and ICC/TUNEL double label methods, the expression of PAI 2 in and the apoptosis of the cultured epidermal keratinocytes treated by TNF ? were detected. Results After the mouse epidermal keratinocytes were incubated with TNF ?, compared with the unshed cells, the expression of PAI 2 in shed cells and the cellular apoptosis increased obviously. The increased PAI 2 expression also appeared in the apoptotic cells, especially in larger and multi angled apoptotic cells. Conclusion In highly differentiated epidermal keratinocytes, TNF ? can enhance the expression of PAI 2 as well as apoptosis. Furthermore, according to the relation with the keratinocytes apoptosis, there are two types of PAI 2 induced by TNF ?, one of which is related to apoptosis, but the other is not.

Objective:To explore blood pressure variability (BPV)characteristics in patients with sustained,masked hypertension (MH)and white coat hypertension (WCH).Methods:A total of 527 cases undergoing physical exami-nation in our hospital from Dec 2010 to Dec 2012 were treated as subjects.According to characteristics of blood pressure (BP),they were divided into sustained hypertension group (SH group,n= 143),MH group (n= 93), WCH group (n=86)and normal control group (NC group,n=205).CV (coefficient of variation)=BPV/mean BP.Results:BP-CV of MH group and SH group were significantly higher than that of NC group [24h systolic blood pressure (SBP)-CV: (27.73±5.36)% vs.(29.83±5.95)% vs.(17.93±4.85)%,24h diastolic blood pressure (DBP)-CV: (23.02±4.63)% vs.(22.69 ± 4.63)% vs.(14.32 ± 4.21)%,daytime (d)SBP-CV: (25.12 ± 4.79)% vs.(25.98±4.73)% vs.(14.97±4.29)%,dDBP-CV:(21.03±4.59)% vs.(20.92±4.53)% vs.(11.79 ±4.43)%,nighttime (n)SBP-CV: (21.52±4.93)% vs.(22.37±4.98)% vs.(11.57±4.19)%,nDBP-CV:(18.79±4.83)% vs.(20.09 ± 5.19)% vs.(6.98 ± 3.69)%],P < 0.01 all;however,there was no significant difference in BP-CV between WCH group and NC group,SH group and MH group (P >0.05).Conclusion:Blood pressure variability significantly rises in patients with sustained and masked hypertension,which may be one of main causes for severe target organ damage in these patients.

This study was aimed to investigate the effect of Rheum tanguticum on expression of serum endothelial nitric oxide synthase (eNOS), endothelin (ET) and 6-keto-prostaglandin F1α (6-Keto-PGF1α) in uric acid nephropathy rat model. After 3 weeks of treatment with different extractions of Rheum tanguticum on uric acid nephropathy rat model, levels of serum BUN, Cr and UA were measured by biochemical analyzer. ELISA method was used to measure the expression of serum eNOS, ET and 6-Keto-PGF1α. Meanwhile, pathological changes of renal tissues were observed by light microscope. The results showed that compared with the normal control group, the levels of serum BUN, Cr, UA and renal index were higher in the model group (P< 0.05). Compared with the model group, the concentration of eNOS in the model group was obviously higher in the rhubarb ethanol extraction group, rhubarb water extraction group, and allopurinol group (P< 0.05). Concentration of ET was obviously reduced in the rhubarb water extraction group and allopurinol group (P< 0.05). There was no statistical difference with the rhubarb ethanol extraction group. There was no significant difference in the concentration of 6-Keto-PGF1α among groups. Lots of inflammatory cells and uratic crystallization were observed by light microscope in renal tissues among rats in the model group. Damages of renal tissues in medication groups were alleviated than the model group. It was concluded that Rheum tanguticumcan alleviate the damage of uratic crystallization and inflammatory cell infiltration, increase the concentration of serum eNOS, and decrease the concentration of serum ET. Thus, it can reduce the damage of renal endothelial cells and protect renal functions. The effect of rhubarb ethanol extraction on reducing ET expression was less than the water extraction.

Objective To investigate the clinical efficacy and toxicity of comparison of the pemetrexed combined with cisplatin and docetaxel of advanced non small cell lung cancer(NSCLC).Methods The clinical data of 102 patients with advanced NSCLC were retrospectively analyzed.Fifty-two patients received pemetrexed combined with cisplatin (Group PC) (pemetrexed 500 mg/m2 intravenous drip in first day,cisplatin 75 mg/m2,intravenous drip in first day to third day,repeated every 21 days); Other 50 patients received the docetaxel combined with cisplatin (Group TP) (docetaxel 75 mg/m2 intravenous drip in first day,cisplatin 75 mg/m2 ntravenous drip in first day to third day,repeated every 21 days).The disease control rate (DCR),progress free survival,median survival time and 1 year survival rate were compared between two groups.Results The efficacy and side effects of all the patients could be evaluated.There was no case with complete remission,43 of partial remission,38 cases of stable and 21 cases of progress.No statistical significance were found between the two groups in DCR (80.8％ (42/52) vs.78.0％ (39/50)),progression-free survival (5.69 vs.4.71 months,P =0.334),median survival time (10.49 vs.10.48 months,P =0.851) and 1 year survival rate (32.0％ vs.24.0％,x2 =1.59,P =0.210).The most common toxicities were arrest of bone marrow and alimentary tract reactions.Pemetrexed could reduce the Leukopenia (P =0.010),the alopecia (P =0.004),the febrile (P =0.024) and tetter (P =0.048); but no significant difference was found in anaemia (P =0.873),thrombocytopenia (P =0.541),nausea and vomiting (P =0.114) and impaired liver function (P =0.403) and impaired renal function (P =0.541).Conclusion Pemetrexed and docetaxel combined with cisplatin for the treatment of advanced NSCLC have similar treatment effects,and the side effect of pemetrexed combined cisplatin is lower.
