AIM　To improve the treatment efficacy of anti-tumor drug mitoxantrone, the conjugation of mitoxantrone-loaded nanospheres and anti-C-erbB-2 monoclonal antibodies were prepared. METHODS Mitoxantrone-loaded nanospheres were prepared with emulsion-heating solidification technique. A heterobifunctional reagent, N-succinimidyl 3-(2-pyridyldithio) propionate (SPDP), was used as the crosslinker of mitoxantrone-loaded nanospheres and anti-C-erbB-2 monoclonal antibodies; pharmaceutical properties of immunonanocapsuls were studied; the conjugates of nanospheres and monoclonal antibodies was confirmed with immunological methods such as slide agglutination test, fluorescent immunossay and rosset formation test, fluorescent staining and scanning electron microscope. RESULTS　Mitoxantrone-loaded nanospheres were spherical, with smooth surface and median diameter of 0.665 micron. When stored at 3-5, 20-25 and 37℃, RH 75% for three months, the appearance, morphology, size distribution, drug loading and in vitro release characteristics showed no significant change and the stability was satisfactory. The size analysis demonstrated that there was no obvious increase in the particle size of nanoparticles after conjugation. Immunological tests indicate highly selective binding of antibody-targeted nanospheres to C-erbB-2-overexpressing cells SK-BR-3. CONCLUSION　The conjugation of mitoxantrone-loaded nanospheres and anti-C-erbB-2 monoclonal antibodies can keep the activity of anti-C-erbB-2 and increase the therapeutic efficacy of anti-mammary cancer drugs.

AIM: To explore the mechanism of the nitric oxide (NO) synthesis induced by human C5b-9 complex in glomerular mesangial cells(MC) of rats. METHODS: The MC of rats were cultured and stimulated with human complement C5b-9 complex to induce TNF? and IL-1?. At the same time, several parameters related to NO synthesis were measured at 3 h, 6 h and 24 h after C5b-9 stimulation. The effects of monoclonal antibodies against TNF? and IL-1? on NO synthesis were examined in this system. RESULTS: TNF? concentration in supernatant from MC in C5b-9 group was higher than that of control group at 6, 24 h after stimulation with C5b-9 complex and reversed by adding anti-TNF? McAb. C5b-9 complex didn't stimulate the release of IL-1? in same system. In addition, the expression of iNOS mRNA in MC was observed at 3 h after stimulation with C5b-9. Levels of iNOS mRNA expression and cGMP in MC and NO - 3/NO - 2 in supernatant from MC in C5b-9 group were higher than those in control group at 6, 24 h after C5b-9 stimulation, these changes were also reversed by adding monoclonal antibody against TNF?. CONCLUSION: C5b-9 complex could induce iNOS mRNA expression at 3 h after C5b-9 stimulation, and the synthesis of NO at 6, 24 h was related to TNF? released from cultured MC of rats by C5b-9 complex to a certain extent.

Objective To investigate the infection of 23 kinds of human papillomavirus ( HPV) subtypes in female cervical epithelium samples and to analyze their relationships with age and results of cyto-logic test in Haikou area. Methods A total of 4 037 local healthy women were enrolled in this study from July 2013 to August 2016, 1 967 of whom received cervical cytology test. Cervical cell samples collected from those women were detected for HPV typing by using PCR-reverse dot blot hybridization. Results (1) The total positive rate of HPV in 4 037 samples was 22. 15% (894 cases), and the detection rates of carci-nogenic, possibly carcinogenic and non-carcinogenic HPV were 16. 13%, 3. 99% and 5. 55% (651, 161 and 224 cases), respectively. The positive rates of 6 genotypes were high, which were HPV52, 53, 81, 51, 16 and 58 in turn. (2) The detection rates of carcinogenic, possibly carcinogenic HPV and some of the gen-otypes (HPV18, 52, 53, 66) increased with age (all P<0. 05). (3) Multiple infection in HPV-positive women accounted for 24. 38% (218/894), in which the infection rates of carcinogenic types declined with age and the numbers of HPV genotypes in carcinogenic infections were negatively correlated with age ( both P<0. 05). (4) Only 2. 49% (49/1 967) of the samples were positive for cervical cytologic test, classified into the ≥ASC-US ( atypical squamous cells of undetermined significance ) group. The detection rates of eight kinds of carcinogenic and two kinds of possibly carcinogenic HPV in≥ASC-US group were significantly higher than those in the negative (no intraepithelial lesion or malignant lesion, NILM) group (all P<0. 05). Conclusion This study indicates that Haikou women have higher rates of HPV infection, especially the eld-erly group. HPV subtype infections present some regional characteristics and are mainly single type infec-tion. Cervical cancer screening should be combined with tests for HPV and cytology analysis to improve its effectiveness.

Objective To investigate the feasibility and efficiency of monitoring noninvasive respiratory effort and respiratory load-capacity ratio in patients undergoing weaning from mechanical ventilation by mean inspiratory pressure(Pi) which were calculated on the basis of the formula, Pi = 5 × P 0.1 × Ti, as well as the noninvasire tension index calculated from Pi(TTIi). Method Totally 12 patients undergoing weaning from mechanical ventilation were enrolled in the study and their underlying diseases included COPD( n = 9), ARDS( n = 2) and status asthmaticus(n = 1) respectively. Esophageal pressure(PesoM) was monitored via the insertion of esophageal balloon and corrected esophageal pressure(Peso) was acquired by subtracting elastic pressure of chest wall from PesoM. P 0.1, Maximal inspiratory pressure on esophageal pressure curve(MIPeso) and on airway pressure curve(MIPaw) was measured with conventional technique. Pi was calculated on Pi = 5 × P 0.1 × Ti. Pi and MIPaw were used to calculate the noninvasive tension-time index TTIi, whereas Peso and MIPeso were used to calculate the invasive counterpart TTIeso. Comparisons, Correlation and Bland-Altman agreement analysis were made between P0.1 and Peso as well as between TIIi and TTIeso. Results There were no significant differences between Pi and Peso as well as between TTIi and TTIeso(P > 0.05) ,and the correlation coefficients were 0.974 and 0.957 respectively. In the agreement analysis, the mean difference between Pi and Peso, and between TTIi and TTIeso were lower than the minimal values of(Peso + PiSB )/2 and of(TIIi + TTIeso)/2, respectively. Conclusions There is a good correlation between Pi and Peso as well as between TTIi and TTIeso, in which Pi is calculated calculated from P 0.1 and in turn the TTIi is calculated from Pi. The noninvasive indices including Pi and TTIi can be used to monitor respiratory effort and respiratory load-capacity in patients undergoing weaning from mechanical ventilation.
