Objective To investigate the expression of caveolin-1 in the sera of esophageal cancer patients , and the possibility of caveolin-1 to be the tumor marker of an esophageal cancer .Methods ⑴Western blot was used to detect the expression of caveolin-1 in esophageal cancer cell EC 109 and EC9706;⑵The sera were collected from 43 esophageal cancer patients , 30 benign esophageal lesions, and 50 healthy control men.Enzyme linked immunosorbent assay (ELISA) was used to detect caveolin-1 in serum.Results⑴Western blot showed that caveolin-1 was detected in two types of esophageal cancer cell lines .The level of caveolin-1 in the poor dif-ferentiated EC109 cell line was mush higher than in the well differentiated EC 9706 cell line ( t =3.08 , P =0.035 ) .⑵ ELISA re-vealed that the median level of serum caveolin-1 in 43 esophageal cancers (0.104 ng/ml) was significantly higher than 30 benign e-sophageal lesions (0.075 ng/ml) or 50 healthy control men (0.081 ng/ml) (χ2 =23.16, P =0.001).Conclusions Caveolin-1 may be the tumor marker of an esophageal cancer as its level in esophageal patients was higher than in benign esophageal lesions pa -tients or healthy control men .

Objective To detect the expression of caveolin-1 and PY14caveolin-1 in different esophageal tissues,and study the relationships between the expressions of caveolin-1 and PY14caveolin-1 with the occurrence and development of esophageal squamous cell carcinoma.Methods The fresh surgical specimens in 60 patients with esophageal squamous cell carcinoma were collected and Western blotting were used to analyze and detect the expressions of caveolin-1 and PY14caveolin-1 in esophageal squamous cell carcinoma,adjacent esophageal tissues and normal esophageal tissues.The expression of cav-1 and PY14caveolin-1 with esophageal squamous cell carcinoma were analyzed.Results The expressions of caveolin-1 and PY14caveolin-1 in esophageal squamous cell carcinoma were much higher than that in adjacent tissues and normal esophageal tissues,and the difference between them was statistically significant(P＜0.05).Conclusion The expression of caveolin-1 and PY14caveolin-1 in esophageal squamous cell carcinoma, adjacent esophageal tissues and normal esophageal tissues decreases successively,it suggests the caveolin-1 and PY14caveolin-1 may be the key of the occurrence and development of esophageal cancer cells and they could be involved in the migration and invasion of esophageal cancer.

Objective To investigate the effect of alprostadil combined with Salvia miltiorrhiza in treatment of hyperlipidemic acute pancreatitis.Methods Patients with high cholesterol of hyperlipidemic acute pancreatitis were randomly divided into control group and treatment group,32 cases in each group.The control group were treated with conventional therapy combined with alprostadil 10μg intravenous injection,the treatment group was given Salvia miltiorrhiza injection 20mL vein infusion on the basis of the control group.The abdominal pain relief time,APACHE -II,C reactive protein levels,prognosis,hospitalization time and cost were compared between the two groups.Results The abdominal pain relief time,APACHE -II score,C reactive protein level in the treatment group were (5.31 ± 1.09)d,(2.34 ±1.18),(48.41 ±22.64)mg/L,which were better than those in the control group (8.16 ±1.39)d, (4,47 ±1.68)and (65.34 ±18.02)mg/L,the differences were statistically significant (t =9.08,0.14,5.84,-0.49,3.31,all P <0.05).There was no difference in mortality between the two groups (P >0.05).The operation rate of control group was 31.25% (10 /32),which was significantly higher than that of the treatment group [6.25%(2 /10)],the total hospitalization time,total cost of the treatment group were (14.50 ±1.55 )d and (4.97 ± 1.00)ten thousand yuan,which were significantly lower than those of the control group (16.78 ±1.83)d and (5.72 ± 1.71)ten thousand yuan,the differences were statistically significant (χ2 =6.65,t =1.00,t =5.39,all P <0.05). Conclusion Alprostadil combined with Salvia miltiorrhiza injection in the treatment of hyperlipidemia hyperlipidemia acute pancreatitis is safe,has good treatment effect,and can shorten the course of disease,reduce patients'hospitaliza-tion time and cost,and effectively improve the cure rate.
