Objective To explore the nursing of polycystic ovary syndrome treated by transvaginal ultrasound small follicular puncture.Methods The treatment and nursing of 58 cases with polycystic ovary syndrome treated by transvaginal ultrasound small follic~ar puncture were summarized.Results Among 58 cases of polycystic ovary syndrome treated by transvaginal ultrasound small follicular puncture,21 cases obtained postoperative pregnancy,the pregnancy rate was 36.20％.Conclusions According to the psychological characteristics of patients with polycystic ovary syndrome treated by transvaginal ultrasound small follicular puncture,good psychological nursing and sufficient preoperative preparation are helpful to reduce the patients' psychological pressure,cooperate with the operation smoothly,and obtain satisfactory clinical effect.

ObjectiveTo observe the treatment effects in 48 cases of advanced lung cancer patients,with the immune therapy of the dendritic cells loading of tumor autologous antigen (DCTAA) combining with the cells induced factor of the killer cells(CIK)from the matched umbilical cord blood cells.MethodsThe peripheral blood mononuclear cell(PBMC)from the matched umbilical cord blood cells was seperated,and induced to CIK and DC with some cytokines in vitro, such as CD3McAb, IL-2, IFN-γ IL-1α, etc. After 12 to 15 days, the amplified CIK cells obtained were obtained, with the strict quality control, infused the CIK cells to the patients body back in six times,about(5-8)×109 CIK cells in each time.In the fifth day of the cultivation,DETAA cells were loaded and DCTAA cells were collected in the eighth day,and then hypodermic injection was done. The patient' s general situation after the immune treatment was observed, such as the size of the tumors, clinical symptom score, the quality of life and immune indexes. Karnofsky score, weight, toxic side effects and the patient's survival were also studied.ResultsIn the 48 cases with the DCTAA-CIK treatment, complete remission (CR), partial remission (PR)was 37 cases, the overall remission rate was 77.1％. The improvement rate of clinical symptom scores was from 78.9 ％ to 84.7 ％, the increasing rate of Karnofsky score was 89.6 ％ (43/48). 1-year survival reached to 80.6 ％. There were significant difference in little toxic side effects(P ＜ 0.01). The proportion of CD3, CD4 and NK cells in peripheral blood cells increased significantly (P ＜ 0.01) after DCTAA-CIK cells treatment[(42.21±6.12)％, (24.42±3.01)％, 0.99±0.34, (24.98±3.02) ％; (71.58±7.64) ％, (37.25±2.13) ％, 1.62±0.45, (35.23±4.11) ％](t = 6.34, 5.67, 0.25, 4.43, P ＜0.01).ConclusionThe DCTAA-CIK immune therapy is benefit for advanced lung cancer,not only improve the immune function but also ameliorate the clinical symptoms.

The valaciclovir was used as the model drug, the bovine serum albumin nanoparticles (BSA-NP) were prepared by desolvation process. Glycyrrhizin (GL) was oxidized by sodium periodate to be conjugated to surface reactive amino groups (SRAG) of the VACV-BSA-NP. Gel filtration method combined with HPLC method verified that GL was covalent coupling to the surface of VACV-BSA-NP with mean 9 GL residues per albumin molecule. The mean diameter of the VACV-BSA-NP-GL was 268 +/- 23 nm, the drug loading was 1.35%, and embedding ratio was 68.76%. The characteristics of release in vitro were in accord with two-phase kinetics. The uptake amount of VACV-BSA-NP-GL by primary cultured rat hepatocytes in vitro was higher, compared to the control-VACV-BSA-NP. 69.89% and 64.82% of the VACV were concentrated in liver at 15 min after i.v. VACV-BSA-NP-GL and VACV-BSA-NP, respectively. There is a significant difference between surface-modified group and control group (P<0.10). VACV-BSA-NP-GL was successfully prepared, which is considered to be a novel drug delivery system for targeting to hepatocytes.
