RNA interference (RNAi), as a new technology of gene therapy, has been used in the studies of many diseases in vitro, however, targeting delivery of small interference RNA (siRNA) is still a bottleneck for clinical therapy of siRNA agents. Aptamer is a group of oligonucleotides with high affinity and targeting, and is becoming another important means of delivery for siRNA. In this review, we summarized siRNA delivery obstacles in vivo and recent attractive developments increatively using cell-internalizing aptamers to deliver siRNAs to target cells.

Castleman disease (CD) is a rare polyclonal lymphoproliferative disorder characterized by enlarged hyperplastic lymph node(s). Unicentric Castleman disease (UCD) is an indolent condition often treated by local approaches. On the contrary, pa-tients with multicentric Castleman disease (MCD) have less favorable prognoses and require systemic treatments. Cytotoxic chemother-apy has been widely used to treat MCD with varying degrees of response because of the toxicity risk of the treatment. The pathogenesis remains unknown;however, most pieces of evidence to date point toward human herpes virus 8 (HHV-8) and deregulated overproduc-tion of interleukin (IL-6). Discovery of putative etiologic factors and targets in MCD, particularly HHV-8, CD20, and IL-6, has translat-ed to the use of rituximab, anti-IL-6-based, and antiviral therapy. Good results have been realized through targeting HHV-8 replication, CD20, and IL-6 pathways. In this article, we reviewed the classification, pathogenesis, and current treatments of CD and provided in-sights into future treatment strategies based on disease biology.

Objective To simulate the solution drought stress conditions with polyethylene glycol (PEG) 6000 for study on the seed germination of Cassia occidentalis.Methods The seed of C.occidentalis was treated with 5% and 10% PEG 6000,respectively,then the germination rate,the activity of superoxide dismutase (SOD),peroxidase (POD),and content of malondialdehyde (MDA) were measured.Results Compared with the same period of the control,soaking with 5% PEG 6000 for 5 h could increase the activity of SOD and POD,decrease the content of MDA.PEG Pretreatment could decrease free radical accumulation and make cell membrane system less damaged in the course of absorbing water in seed.Conclusion Soaking with 5% PEG 6000 for 5 h could increase the seed germination rate of C.occidentalis.

Objective To compare the efficacy and adverse reaction of teniposide (VM-26) plus carboplatin (TC regimen) and etoposide (VP-16) plus carboplatin (EC regimen) in treatment of newly diagnosed small cell lung cancer (SCLC), and the possible role of VM-26 on prevention of brain metastasis of SCLC. Methods A total of 102 previously untreated SCLC patients without brain metastasis were divided into VP-16 group received EC regimen (n=64) and VM-26 group received TC regimen(n=38). The carboplatin dosages in two groups were calculated by blood concentration-area under the curve(AUC)=5, and intravenous infusion of 1 h for the first day. In VM-26 group, VM-26 70 mg/m2+normal saline 500 mL was intravenously infused of 2 h for 1-3 days. VP-16 100 mg/m2+normal saline 500 mL was given to VP-16 group, 1 h for 1-3 days. Twenty-one day was for 1 treatment cycle. The curative effect, prognosis and adverse reaction were compared between two groups. Results The overall response rates (ORR) and disease control rates (DCR) were 78.9%(30/38) and 97.4%(37/38) in VM-26 group, respectively, and 76.6%(49/64) and 95.3%(61/64) in VP-16 group, respectively, with no significant differences between the two groups (χ2=0.078 and 0.283, P<0.05). The median progression-free survival (PFS) was 10 months (95%CI 7.4-12.6) in VM-26 group and 9 months (95%CI 6.4-11.6) in VP-16 group (χ2=0.029,P=0.866). The median overall survival (OS) was 18 months (95%CI 16.5-19.5) and 16 months (95%CI 9.9-22.1) in VM-26 group and VP-16 group (χ2=0.217,P=0.642), respectively. The survival rates for 1,2 and 3 years were 73.7%, 36.8%and 18.4%in VM-26 group, and 71.9%, 37.5%and 18.8%in VP-16 group, respectively, with no significant differences between the two groups (P>0.05). The brain metastasis rate was significantly higher in VP-16 group [43.8%(28/64)] than that of VP-26 group [21.1%(8/38),χ2=5.379,P=0.02). The adverse reactions were mainly grade 1/2 bone marrow suppression in two groups. Conclusion TC is a highly active regimen for treatment of SCLC. There is no difference in the ef?fectiveness and adverse reactions versus EC. Application of VM-26 can reduce the incidence of brain metastasis in SCLC patients.
