Objective: To evaluate the effect and safety of molecular targeted therapy of apatinib mesylate combined with multiple antigen stimulatiing cellular therapy in treatment of osteosarcoma and soft tissue sarcoma. Methods:Six patients with sarcoma were collected by the failure of surgery, radiation and chemotherapy treatment or refusal surgery, radiation and chemotherapy, and at least one month from the last treatment of surgery, radiation and chemotherapy. All of the patients at least received three cycle MASCTTM . From Day 1,everyone were given Apatinib 500 mg,po,qd ,until the disease progression. To measure the patient’s quality of life depending on EORTC QLQ-C30,meanwhile,detecting the cellular immunity function and circulating tumor cells(CTCs) of patients before treatment and one month after 3 cycle MASCTTM . At last, monitoring the cellular immune responses by the Enzyme-linked immuno spot ( ELISPOT) assay. Results: All of the four patients completed the treatment of 3 cycle MASCTTM . Only one patient reduced apatinib from 500 mg to 250 mg because of palmar-plantar erythrodyses-thesia. The response rates of the four patients received MASCTTM and apatinib mesylate after treatment were 1 for complete response (CR),3 for partial response (PR). The life quality and cellular immunity function were improved in all of the patients. ELISPOT assay suggested that the majority of antigen peptides could induce specific cytotoxic T lymphocytes( CTLs) response. The Progression-Free-Survival ( PFS) of four patients received MASCTTM and apatinib mesylate was 7,6,9 and 4 months ,while the response rates of the two patients received apatinib mesylate were 1 for ( Stable disease) SD,one for ( Progression disease) PD. And PFS of the two patients were one month and two months. Conclusion:Combination of MASCTTM and apatinib mesylate is safe,effective and were good prospects for application.

Objective To compare the effect of perineal cleansing with the potassium permanganate or sterile water on mid- stream urine culture. Methods Mid- stream specimens of urine were obtained from inpatients in our hospital between January 2002 and December 2006. All these patients may be diag-nosed as urinary tract infection. The urine specimens were divided into the potassium permanganate group (n=1572, the sterilization group) and the sterile water group (n=544). The change of positive and contami-nation rate of mid-stream urine culture from the specimens was observed. More than two kinds of germs in one urine specimen were defined as contamination. Results 830 patients with urinary tract infection had been enrolled. 2116 specimens were collected and 531 strains of causative organism were detected. The positive rate of the sterilization group and the sterile water group was 20.04% and 39.71%, respectively,and such difference was significant. The rate of identical causative organism from the same patient whose spec-imen was cultivated twice in the sterilization group was 0.012% and the rate was 0.105% in the sterile water group. The difference was significant. The rate of different or one kind of causative organism from the same patient whose specimen was cultivated twice in these two groups hadn't significant deviation. The contami-nation rate of the sterilization group (0.028%) was significantly higher than that of the sterile water group (0.007%). Conclusions Perineal cleansing with sterile water can reduce the false negative rate of mid-stream urine culture without increasing the contamination rate. Potassium permanganate sterilization is re-sponsible for the high false-negative in mid-stream urine culture.

Objective To study the expressions of DD3 mRNA and PSA mRNA in the prostate tissues and its diagnostic value in prostate cancer (PCa). Methods DD3 mRNA and PSA mRNA were detected by real-time fluorescent quantitative reverse transcription polymerase chain reaction ( FQ-RT-PCR) based on Taqman technique in the tissues of 21 cases of PCa and 39 cases of BPH. The receiver operating characteristic (ROC) curve was used to evaluate the diagnostic efficacy of DD3 mRNA, PSA mRNA and DD3 mRNA/PSA mRNA. Results The expressions of DD3 mRNA and PSA mRNA, and DD3 mRNA/ PSA mRNA were significantly higher in PCa tissues than those in BPH tissues ( P 0.05 for all). The AUC-ROC of DD3 mRNA,PSA mRNA and DD3 mRNA/PSA mRNA were 0. 937 (95% CI,0. 879 -0. 995) , 0.755(95% CI,0.629 -0.880) and 0.839 (95%CI,0.738 -0.940),respectively. The sensitivity for DD3 mRNA,PSA mRNA and DD3 mRNA/PSA mRNA was 90. 5% ,81. 0% and 81. 0% , respectively, and the specificity was 85.0% ,62.0% and 66.7% at cutoff value of 1.4?105 copies/mg tissue,3.0?107 copies/ mg tissue and 5. 0?10-3,respectively. The sensitivity and specificity of simultaneous detection for DD3 mRNA and PSA mRNA were 100% and 85.0%. Conclusions Both DD3 mRNA and PSA mRNA expressions were significantly higher in PCa tissues than those in BPH tissues; and the quantitative detection of DD3 mRNA is more helpful for the diagnosis. The simultaneous detection of DD3 mRNA and PSA mRNA can improve the sensitivity in the diagnosis of PCa.

The experiment was conducted to prepare chitosan nanoparticles (CNP), to entrap VRMIL-2 with CNP, the eukaryotic VR1020 expression plasmid containing murine IL-2 gene (mlL-2), and to investigate the expression in vivo and the regulatory effect of mIL-2 on immune-response and immuno-protection in mice inoculated muscularly with CNP entrapped VMIL-2 at 21 days old. The results showed that IgG, IgM and IgA contents increased to different degrees in the sera from the inoculated mice, which were remarkably higher than those of the controls inoculated VR1020 packed with CNP (P<0.05); so were the IL-2, IL-4 and IL-6 contents in the sera of the immunized mice. The number of white blood cells and lymphocytes significantly increased respectively in the vaccinated mice, compared with those of controls. These mice were orally challenged with virulent E. coli 35 days post-inoculation, and all the immune responses were significantly higher than those of the control except the number of neutrophils. The mice inoculated with VRMIL-2 survived healthily, while the mice of control group were ill with the evident lesions. Although there are no remarkable differences between the cellular and humoral immune indexes of mice inoculated with CNP-VRMIL-2 and nude VRMIL-2 (P>0.05), the dosage of CNP-VRMIL-2 is only one fifth of the VRMIL-2. These indicated that entrapment of mIL-2 gene with chitosan nanoparticles could remarkably enhance the expression of mIL-2 in vivo, and significantly raise the levels of cellular and humoral immune, and increase the resistance of mice against E. coli infection. The results suggested that chitosan nanoparticles and IL-2 gene could be used as an effective immunoenhancer to increase the immunity of animals against infection.

OBJECTIVETo investigate the attitude and sexual behavior status and change among HIV positive female workers in entertainment sites in Kaiyuan city, Yunnan province, China. The key information should be applied in the integrated intervention program in future.
METHODSA cohort survey among HIV positive female workers was conducted during 12 months, between 2010 and 2012. All the risk sexual behavior and attitude were collected for assessment for the potential secondary transmission to sexual partners.
RESULTSOf 99 HIV positive women who sell sex in Kaiyuan city, 99 participated in the survey at baseline, 80, 80, 75, and 75 at 3-, 6-, 9-, and 12-month follow-ups. The percentage of participants who reported consistently used condoms in the last one month ranged between 94.5% and 95.5%. The client volume in the last one month, income per sex and age group were significant related with non-insistent condom use with their clients.
CONCLUSIONIt was suggested that integrated intervention program package should include 100 percent condom use promotion for the HIV positive FSW with all sexual partners, and also, include socially support involved.
