ObjectiveTo evaluate the antitumor effects of lymphocytes from hepatic porta lymph node co cultured with staphylococcal enterotoxin A(SEA)?MethodsLymphocytes isolated from lymph node of 5 HCC patients were co cultured with SEA. The proliferation and cytotoxicity of the lymphocytes were observed. Flow cytometer was used to detect the expression of CD3?CD4 and CD8 on the surface of the lymphocytes. TNF ? and IFN ? released into the culture medium were measured by the method of ELISA. The results were compared with that yielded from TILs of the individual patients. ResultsCultured in the presence of SEA, there was a sharp rise of T cells, especially CD8 + cells. Cytotoxic activity was increased. TNF ? and IFN ? were predominantly produced in the first week.ConclusionsLymphocytes from lymph node activated by SEA were armed with an increased antitumor efficacy.

The purpose of this study was to investigate the pharmacokinetic interaction between sunitinib and ramipril in rats. Eighteen male SD rats were divided into three groups, with each group being assigned to orally receive sunitinib, ramipril, sunitinib and ramipril, respectively, for ten days. Blood samples were collected at dif-ferent times after first-day and tenth-day administration. The concentrations of ramiprilat and sunitinib in rat plasma were determined by LC/MS/MS and the pharmacokinetic parameters were calculated and statistically analyzed. Compared with the administration of ramipril alone, after a single-dose combined administration, tmax of ramiprilat decreased significantly and t1/2 prolonged, while AUC0-∞ remained unchanged. These results indicated that the ab-sorption rate of ramiprilat increased and the elimination rate decreased, but total absorption degree was not changed. After multiple-dose administrations, CL of ramiprilat decreased and AUC0-∞ increased obviously. It sug-gested that accumulation of ramiprilat occurred in body and the drug elimination became slower. No obvious difference of sunitinib pharmacokinetic behavior was found when it was given in combination with ramipril after a single-dose administration or multiple-dose administration. Sunitinib decreased the elimination of ramiprilat after co-administration in company with drug accumulation in body after multiple-dose co-administration. The study showed that there were pharmacokinetic interactions between sunitinib and ramipril in SD rats.

In this study, 31 Notopterygium incisum populations were analyzed using ITS sequences to investigate the genetic structure. The results showed that: the ITS region ranged in size from 634 to 635 bp and base composition was with high G + C content of 57.8%. Thirty-one polymorphic sites were detected from 402 sequences of 31 populations of N. incisum, and the proportion of polymorphic sites was 4.88%, in which parsimony informative sites were up to 12. And 31 haplotypes were identified based on these polymorphic sites. Molecular variance analysis (AMOVA) indicated that high genetic differentiation (57%) existed among population, and gene flow was low (N(m) = 0.38) among populations. Phylogenetic relationships of 31 haplotypes were analyzed using NJ method with N. forbesiias an out-group. Phylogenetic analysis showed that 31 haplotypes from different populations mixed together and did not form distinct geographically separated clades.

?AlM: To evaluate the clinical efficacy of posterior continuous curvilinear capsulorhexis ( PCCC ) combined with anterior vitrectomy in preventing posterior capsule opacification of congenital cataract surgery.
?METHODS:Postoperative clinical follow-up data of 82 cases ( 87 eyes ) with congenital cataract treated in Eye Center of our hospital from January 2011 to August 2014 were retrospectively analyzed. The patients were divided into the surgical control group ( 38 cases, 40 eyes, recieved phacoemulsification + PCCC ) and the study group ( 44 cases, 47 eyes, accepted phacoemulsification+ PCCC + anterior vitrectomy). The incidence of central optic axis opaque and postoperative visual acuity distribution were recorded at 1a follow - up. lntraoperative and postoperative complications were observed.
?RESULTS:The rate of central optic axis opaque grade 0 in control group was 37. 5%, compared to 76. 6% in study groups. The opacity distribution ratio of grade 1,2,3 and 4 in study group were lower than that of control group, and the central optic axis opacity distribution ratio in study group was significantly better than that of control group (P<0. 05). The 19 eyes(47. 5%) of visual acuity testing ≤0. 5 in control group , was higher than the 7 eyes(14. 89%) of that in the study group, The 21 eyes (52. 5%) of visual acuity testing >0. 5 in control group was lower than the 40 eyes ( 85. 11%) of that in study group. The visual acuity between two groups has statistical significance difference after 1a follow-up ( P<0. 05 ) , and the visual acuity in study group was significantly better than that in the control group. The postoperative intraocular pressure at 1mo and 1a follow-up was lower than before operation in two groups ( P<0. 05), but there was no significant difference between two groups in intraocular pressure (P<0. 05).
?CONCLUSlON: Combination of phacoemulsification, PCCC and anterior vitrectomy presents reliable clinical effects on postoperative central optic axis opacity distribution ratio and visual acuity, and it should be adopted to prevent the occurrence of posterior capsule opacification.

AIM To prepare diosgenin nanosuspensions.METHODS The nanosuspensions prepared by media milling method were solidificated by freeze drying method.With particle size and polydispersity index (PDI) as evaluation indices,stabilizer kind,ratio of diosgenin to stabilizer,ratio of preliminary nanosuspension volume to grinding bead amount,milling time,lyoprotectant kind and its amount as influencing factors,single factor test was applied to screening preparation and solidification processes.The morphology of nanosuspensions was observed,then the particle sizes and polydispersity indices of nanosuspensions and freeze-dried powder were determined.RESULTS The optimal conditions were determined to be 6:1 for ratio of diosgenin to Pluronic F127 (stabilizer Ⅰ),50:1 for ratio of diogenin to sodium dodecyl sulfate (SDS,stabilizer Ⅱ),1:4 for ratio of preliminary nanosuspension volume to grinding bead amount,120 min for milling time,and 8％ PEG-6000 and 2％ mannitol as lyoprotectants.The average particle size and polydispersity index of rod-like or flaky nanosuspensions were (348.1 ±14.2) nm and 0.244 ± 0.059,respectively,which were lower than those of freeze-dried powder.At room temperature,the particle sizes of nanosuspensions and freeze-dried powder remained stable within 35 d and 3 months,respectively.CONCLUSION The physical stability of diosgenin freeze-dried powder is superior to that of its nanosuspensions,which can be used after being reconstituted.

Objective To investigate the expression of BAMBI in pancreatic carcinoma tissue and its clinical value.Methods Expression of BAMBI was detected by immunohistochemistry in 69 cases of pancreatic cancer and 15 normal pancreatic samples.The survival and its association with clinicopathologic parameters were analyzed.Results The expression of BAMBI in the cancer tissue was much higher than that in the normal tissues (56.5％ vs 16.7％,P ＜0.01).The expression of BAMBI was not associated with age,sex and tumor size,differentiation,but expression of BAMBI in patient with lymph node metastasis was higher than that in patient without lymph node metastasis (67.4％ vs 38.5％,P =0.019),the expression of BAMBI in TNM stage Ⅲ was higher than that in stage Ⅰ + Ⅱ (75.0％ vs 31.0％,P =0.001).The median survival of BAMBI-positive group (6 months) was lower than that of BAMBI-negative group (10 months).Conclusions BAMBI is over-expressed in pancreatic carcinoma,and its expression is associated with lymph node metastasis,TNM staging,differentiation and prognosis.
