Objective To observe the therapeutic effects and toxicities of bone marrow-sparing intensity-modulated radiation therapy (BMS-IMRT) for postoperative cervical cancer.Methods From January 2011 to June 2012,totally 70 postoperative patients with cervical cancer were divided into BMS-IMRT group with 34 cases and IMRT group with 36 cases randomly.External whole pelvic intensitymodulated irradiation combined with chemotherapy was carried out for all patients.The planning target volume received a dose of 45 Gy/25 fractions in all patients.Delineation of the pelvis and limitation dose were carried out in BMS-IMRT group:the pelvis V30 ≤ 50％.All cases received chemotherapy with cisplatin (40 mg/m2) once a week concurrently with radiotherapy.Results Treatment was completed in 67 patients,as the other 3 patients stopped chemotherapy because of myelosuppression.There was no statistically significant differences between two groups for the 2-year local control survival(LCS)and overall survival(OS),alimentary tract toxicity and urinary toxicity.IMRT group had more serious hematologic toxicity than BMS-IMRT group,with statistically significant difference (x2 =14.355,P ＜ 0.05).Conclusions The postoperative cervical cancer patients with poor prognostic factors who undergo concurrent chemoradiotherapy,IMRT group has more serious hematologic toxicity than BMS-IMRT group.The short-term effect and other toxicities reaction are similar between two groups.

The preparation method, serum stability, efficiency of cellular uptake and apoptosis induction of the cell penetrating peptide TAT and cleavable PEG co-modified liposomes loaded with paclitaxel (C-TAT-Lipo) were investigated. The best preparation procedure was performed by orthogonal test based on single factor screening method. First, the paclitaxel (PTX)-loaded liposomes were prepared by filming-rehydration method, evaluated with entrapment efficiency and polydispersity index. The morphology of C-TAT-Lipo was characterized by transmission electron microscopy. Turbidity variations were monitored in the presence of fetal bovine serum (FBS) to evaluate the serum stability of the liposomes developed here. Next, the efficiency of cellular uptake of different Rho-PE-labeled liposomes on B16F1 cells in vitro was evaluated by confocal laser scanning microscopy (CLSM) and flow cytometry. The quantitative analysis of apoptosis induced by different PTX-loaded liposomes was performed by Annexin V-FITC/PI double staining. The optimal formulation was as follows: Chol : lipid: 1 : 8 (molar ratio); drug : lipid: 1 : 40 (mass ratio); lipid concentration: 3 mmol x L(-1); temperature of hydration: 25 degrees C. The mean size and polydispersity index of C-TAT-Lipo were about (97.97 +/- 3.68) nm and 0.196 +/- 0.037, the zeta potential was (-0.89 +/- 0.45) mV, the entrapment efficiency of paclitaxel was (90.16 +/- 1.53)%. The particle sizes did not exhibit significant variations in 50% FBS over 24 h at 37 degrees C. The efficiency of cellular uptake of the C-TAT-Lipo increased 1.40 fold following the cleavage of PEG. Apoptosis analysis showed 59.3% increase of the apoptosis and necrosis profile of C-TAT-Lipo after the detachment of PEG shells, which was markedly higher than that of N-TAT-LP with or without glutathione and SL, respectively. The results indicate that the C-TAT-Lipo is successfully prepared by filming-rehydration method and shows significant antitumor activities.

Background: The conventional therapy for chronic hepatitis C is the combination of interferon-alpha and ribavirin. However, it has some adverse effects and does not response to some patients, and it is also very expensive. Objective: To assess the efficacy and safety of Chinese medicinal herbs for chronic hepatitis C virus infection. Search strategy: Electronic and manual searches were conducted and the search ended in July 2009. Inclusion criteria: We included randomized clinical trials testing Chinese herbal medicine vs placebo, non-specific treatment, antiviral treatment, or Chinese herbal medicine combined with antiviral treatment vs antiviral treatment alone. Data extraction and analysis: Selection of trials for inclusion, assessment of methodological quality, data extraction and data syntheses were conducted according to the protocol of a Cochrane systematic review by the authors. Results: Fifty-one randomized trials (involving 3 678 patients) with various methodological quality were included. The studies published in English had good quality, while studies published in Chinese were of poor quality. The pooled results showed that Chinese herbal medicine alone or in combination with antiviral treatment was generally better than non-specific treatment or antiviral treatment alone, and herbal medicine appeared equal to antiviral treatment regarding comprehensive clinical effect in terms of symptoms, liver function and virological response. Regarding virological response including loss of serum hepatitis C virus (HCV) RNA and anti-HCV antibodies, herbal medicine was better than non-specific treatment, equal to antiviral treatment, and the combination of herbs and antiviral treatment was better than antiviral treatment alone. Similar positive findings were found for liver function improvement. Adverse effects were observed among herbal injections and interferon treatment, and few cases had severe adverse effects. Conclusion: Herbal medicines included in this review have effects in improving symptoms, liver function, and loss of HCV markers in patients with chronic hepatitis C. However, for majority of the included trials were published in Chinese and had low quality, the promising effects from some herbs need to be confirmed in rigorous clinical trials, and the design and reporting of trials should follow international standards.
