Cu2O micro-crystals with different morphologies (including three branching structures) weresynthesized through hydrothermal method by using sodium tartrate as chelating reagent. Branchinggrowth patterns of Cu2O microcrystals have a strong dependence on the amount of sodium tartrate. These different Cu2O microcrystals were used as catalysts to promote the thermal decomposition ofammonium perchlorate (AP). The thermal decomposition of AP in the presence or absence of Cu2Omicro-crystals was investigated non-isothermally through thermogravimetry and differential scanningcalorimetry (DSC). The data obtained from DSC were applied for the calculation and comparison of thekinetic parameters of AP decomposition process through a model-free approach.

Objective: The purpose of this study was to assess prognosis after resection of giant tumors (including lobectomy or pneumonectomy) in the mediastinum. Materials and Methods: Patients with resection of a giant tumor in the mediastinum of the thoracic cavity received ICU treatment including dynamic monitoring of vital signs, arterial blood pressure and CVP detection, determination of hemorrhage, pulmonary function and blood gas assay, treatment of relevant complications, examination and treatment with fiber optic bronchoscopy, transfusion and hemostasis as well as postoperative removal of ventilators by invasive and non-invasive sequential mechanical ventilation technologies. Results: Six patients were rehabilitated successfully after ICU treatment with controlled postoperative errhysis and pulmonary infection by examination and treatment with fiber optic bronchoscopy without second application of ventilators and tubes after sequential mechanical ventilation technology. One patient died from multiple organ failure under ICU treatment due to postoperative active hemorrhage after second operative hemostasis. Conclusions: During peri-operative period of resection of giant tumor (including lobectomy or pneumonectomy) in mediastinum ofthe thoracic cavity, the ICU plays an important role in dynamic monitoring of vital signs, treatment of postoperative stress state, postoperative hemostasis and successful removal of ventilators after sequential mechanical ventilation.

Objective: To investigate the prevalence of genital high-risk human papillomavirus (HR-HPV) in male sexual partners of HR-HPV infected women and the concordance of viral types in couples in China, and comprehend the role of men play in HPV transmission to women. Methods/Materials: 94 asymptomatic women and their husbands from rural Chaozhou participated in epidemiologic screening for HPV infection. Cervical cells from females were collected for high risk HPV screening by real time-PCR, and they were positive for at least 1 of 13 HR-HPV subtypes, then these samples were genotyped. Approximately one mouth later, penile epithelial cells from 94 asymptomatic husbands were collected for HPV genotyping. At the same time, a cross-sectional study was conducted in 366 male patients from sexually transmitted disease (STD) outpatient clinic in China for the prevalence of genital HR-HPV infection in men having frequent sex behavior. Penial epithelial cells were collected for HPV 6/11 and HPV 16/18 detection by fluorescent real-time quantified PCR. Results: Among 94 couples, the prevalence of genital HR-HPV infection in men whose wife was positive for cervical HR-HPV was 5.32% (5/94). Only 2.63% (2/76) had the same high risk viral type presented by their wife. HPV 16 proved to be the most prevalent viral type in men and in couples. Of 366 male patients from STD outpatient clinic, the prevalence of HPV 16/18 infection in men with or without HPV 6/11 was 6.85% and 8.16%, respectively. The incidence of HPV 16/18 was higher in men aged more than 35 years than the young men (18-35 years). Conclusion: The prevalence of genital HR-HPV infection in male sexual partners of HPV-positive women in China was lower than that expected, and the concordance of high risk viral type between couples was extremely low. These data suggested that infected men consitute an important viral reservoir, contributing to transmission of HR-HPV to women and maintenance of infection, but HR-HPV infection may be less likely to persist in men than in women.

A series of 4′-N-substituted (aminomethyl)benzoate derivatives of scutellarein were designed and synthesized. Evaluation of their physiochemical properties showed that the designed target compounds 5a–e exhibit higher chemical stability and aqueous solubility than scutellarin and scutellarein. The permeability (Papp AP to BL ) of 5c–e in Caco-2 cells were 2.8, 8.1, and 12.6 times higher than that of scutellarin and 1.3, 4.1, and 6.0 times higher than that of scutellarein; especially, 5e had the highest P app AP to BL value (7.19 ± 0.31 × 10−6 cm/s) and the lowest ER (P app BL to AP /P app AP to BL ) value of 0.17. In vitro antioxidative evaluation results revealed that 5e could protect against H2O2 -induced PC12 cells’ oxidative damage by attenuating mitochondrial membrane potential loss and decreasing H2O2 -induced reactive oxygen species (ROS) production.

Tuberculosis (TB) has been a major world-wide cause of death for centuries. One-third of the world’s population is infected with Mycobacterium tuberculosis (M.tb), the etiologic agent of TB. The development of potent new anti-TB drugs is urgently needed. The major M.tb surface lipoglycans, mannose-capped Lipoarabinomannan (ManLAM) had immunosuppressive effects during M.tb infection. In this study, aptamer ZXL1 which specifically bound to ManLAM from the virulent strain M.tb H37Rv was screened out by Systematic Evolution of Ligands by EXponential enrichment (SELEX). The binding affinity of ZXL1 to ManLAM was measured as 8.907X10-8 M of quilibrium dissociation constant (Kd) value by surface plasmon resonance (SPR) analysis. We found that aptamer ZXL1 prevented the ManLAM-induced immunosuppressive effects on DCs and inhibited M. tb entry into macrophages. More importantly, we found that single injection of aptamer ZXL1 significantly prolonged the survival rate of infected mice, and prevent the infected rhesus monkeys from weight loss. The Bacterial numbers were significantly lower in the lungs and spleens in ZXL1-treated groups. These results suggest that aptamer ZXL1 can be used as antimycobacterial agent or as TB vaccine adjuvent.

Four new acylated triterpene glycosides with aliphatic chains (4–7) as well as five known triterpenoids were isolated from the flower buds of Staphylea bumalda with bioassay guidance. Their structures were determined on the basis of spectral techniques, including IR, 1D and 2D NMR, and HR-APCI-MS. Most compounds (except 8) were isolated from S. bumalda for the first time. Additionally, the neuroprotective effects of 1 and 4–9 on suckling rat primary cultured hippocampal neurons against H2O2-induced injury were evaluated in vitro. The four new triterpenoids (4–7) showed neuroprotective effects, which increased the cell viability to over 74% at different concentrations, which was higher than the negative control (59%), while compounds 1 and 8–9 exhibited cytotoxic activity.
