Objective To evaluate the clinical value of CT-guided interstitial implantation of ~(125)I seeds for the treatment of pulmonary carcinoma. Methods A total of 18 patients with pulmonary carcinoma underwent CT-guided interstitial implantation of ~(125)I seeds. According to the size of tumor,effective dose, and optimal quantity of ~(125)I seeds to the patient that were computed by a developed algorithm in Treatment Planning System (TPS), the ~(125)I seeds were implanted into the tumor tissues under the guidance of spiral CT. The patients were reexamined by CT 2 months after the operation and were followed up for 6 months. Results A total of 812 seeds were implanted into the 18 lesions in the 18 cases (45.1 seeds per case in average). The CT scan performed 2 months after the operation showed CR in 7 cases, PR in 10, and NC in 1. The total effectiveness (CR+PR) rate was 94% (17/18). Conclusions CT-guided interstitial implantation of ~(125)I seeds is a effective, minimally invasive, and low toxic method for valid and minimally traumatic treatment for middle- and late-stage lung cancer. Further application and long-term observation are necessary.

TNF-?,a pleiotropic cytokine with strong proinflammatory and immunomodulatory properties is known to play an important role in inflammatory bowel disease(IBD).The biological effects of TNF-? are elicited by binding to its two cognate recepters,TNFR1 and TNFR2.For a long time,TNF-R1 was considered to be the predominant mediator of TNF-signaling,whereas TNF-R2 was ascribed only auxilliary function.However,there is increasing clinical and experimental evidence for an important independent role of TNF-?/TNFR2 signaling in chronic inflammatory conditions of IBD.The elucidation of the different effects of TNF-signaling in IBD will lead to a better understanding ot the pathogenesis of these diseases and will be the basis for the development of more specific and more efficient therapeutic approaches.

Objective To isolate side population (SP) cells from an established ovarian cancer (OC)cell line,characterize these cells,and examine their drug resistance. Methods SP and non-SP (NSP) cells were isolated by fluorescence-activated cell sorting (FACS),and cultured in differential conditions,then detected their SP ratio to compare their capability of differentiation and self-renewal. Moreover,SP and NSP cell tumorigenesis was examined by subcutaneous and intraperitoneal injection of these cells to nonobes ediabetic(NOD)-severe combined immundeficient(SCID)mice. Drug resistance to cisplatin was examined by cell counting kit-8 (CCK-8).Results SP cells could be isolated stablly and insistently. There was(4.81 ± 0.43)%of SP cells in the established OC cell line and(4.89 ± 0.33)%of SP cells after cultured the isolated SP cells in differentiation condition,and there was no significant different between these two quantities (P>0.05). However,after cultured the NSP cells,there was only (0.10 ± 0.03)%of SP cells which was significantly lower than that contained in the OC cell line(P<0.01). In the tumorigenesis assay 1.0 × 103 SP cells were injected subcutaneously and formed the xenografted tumors in 6 weeks(3/3),and 1.0×104 NSP cells were injected subcutaneously and did not form xenografted tumors in 12 weeks(0). The tumorigenic capability of SP cells was higher than that of NSP cells(P<0.01). Both the original and the xenografted tumors were low differentiated serous cystadenocarcinomas and expressed the ovarian serous cystadenocarcinomas CA125 marker after stained by HE and immunohistochemistry. Simultaneously,the SP cells were also capable to form tumors as shown by intraperitoneal injection. In the drug resistance assay shown that the 50% inhibitory concentration (IC50) of the SP and NSP cells were respectively(2.33 ± 0.14)μg/ml and(1.60 ± 0.04)μg/ml(P<0.05). After treated the unsorted OC cells with cisplatin,the quantity of SP cells increased to(40.10 ± 4.22)%and there was significant difference,when compared to the untreated cells which was(4.81±0.43)%(P<0.01). The SP cells survival rate was(58.7± 3.3)%when treated with cisplatin at its IC50 dose,and the rate decreased to(7.2±1.3)%(P<0.01)when verapamil was present. Conclusions The SP cells could be isolated from the established OC cell line. They had the capacities of self-renewal,differentiation,and tumorigenesis,and the new tumor demonstrated the original tumor′s phenotype. The SP cells also had stem cells′ biological characteristics and is resistant to cisplatin.

For attracting more social charity funding into the health field, in-depth interviews are conducted into four health foundations in Beijing, presenting three aspects of existing problems and obstacles in the foundations devel-opment in this article. Firstly, the foundations have low effect in fundraising, poor information publication, little com-munication between other facilities and vague mechanism in donation. Secondly, the social public has erroneous views leading to deviant behavior. Finally, some annual inspection standards of the foundation are not suitable for the health field. Based on the above analysis, suggestions about how to improve transparency and fundraising ability in foundations and change the public erroneous views in donation are proposed. The governments might be suggested to get more relax-ed on the annual inspection standards of the foundations, and build an information platform in healthcare field as well.
