Two new high-nitrogen energetic compounds ZTO·2H2O and ZTO(phen)·H2O have been synthesized (where ZTO = 4,4-azo-1,2,4-triazol-5-one and phen = 1,10-phenanthroline). The crystal structure, elemental analysis and IR spectroscopy are presented. Compound 1 ZTO·2H2O crystallizes in the orthorhombic crystal system with space group Pnna and compound 2 ZTO(phen)·H2O in the triclinic crystal system with space group P-1. In ZTO(phen)·H2O, there is intermolecular hydrogen bonds between the -NH group of ZTO molecule (as donor) and N atom of phen molecule (as acceptor). Thermal decomposition process is studied by applying the differential scanning calorimetry (DSC) and thermo thermogravimetric differential analysis (TG-DTG). The DSC curve shows that there is one exothermic peak in ZTO·2H2O and ZTO(phen)·H2O, respectively. The critical temperature of thermal explosion (Tb) for ZTO·2H2O and ZTO(phen)·H2O is 282.21 oC and 195.94 oC, respectively.

Konjac glucomannan (KGM)/galactoglucomannan (GGM) nanofiber membranes were obtained through electrospinning technology. Rheological properties of KGM/GGM solutions were observed by using a rotary rheometer. The apparent morphological, characteristic group and thermal stability of nanofiber membranes were studied through scanning electron microscopy (SEM), Fourier transform infrared spectoscopy (FTIR) and differential scanning calorimeter (DSC) respectively. The physical and mechanical properties were also evaluated. Results revealed that the addition of GGM did not significantly affect the rheological properties of electrospinning solution. Increase in the amount of GGM in the nanofiber membrane resulted in gradual smoothening, uniformity and decrease in the number of nodes. KGM interacts with GGM through hydrogen-bond. Addition of GGM markedly enhanced the thermal stability, physical and mechanical properties of the nanofiber membrane. The study showed that the KGM/GGM nanofiber membrane have good potential for use in developing membrane based materials.

Cervical cancer is one the most common malignancies among females. In recent years, its incidence rate has shown a rising trend in some countries so that development of anticancer drugs for cervical cancer is an urgent priority. In our recent anticancer drug discovery screen, 1, 2-di (quinazolin-4-yl)diselane (LG003) was found to possess wide spectrum anticancer efficacy. In the present work, the in vitro anticancer activity of LG003 was evaluated in the SiHa cervical cancer cell line. Compared with commercial anticancer drugs 10-hydroxycamptothecin, epirubicin hydrochloride, taxol and oxaliplatin, LG003 showed better anticancer activity. Furthermore, inhibition effects were time- and dose-dependent. Morphological observation exhibited LG003 treatment results in apoptosis like shrinking and blebbing, and cell membrane damage. Lactate dehydrogenase release assay revealed that LG003 exerts such effects in SiHa cells through a physiology pathway rather than cytotoxicity, which suggests that title compound LG003 can be a potential candidate agent for cervical cancer.

Oral squamous cell carcinoma (OSCC) is predominantly a disease of middle-aged men with long-term exposure to tobacco and alcohol. An increasing trend has been reported at a younger age worldwide. Clinical records of 100 patients under the age of 45 years treated specifically for oral cavity SCC in our hospital during a 10-year period were retrospectively analyzed to calculate the survival rates. An obvious male predominance coincided with smoking trend among Chinese young individuals and female patients were more likely to have no traditional risk factors such as smoking or drinking. The 5-year overall survival rate and disease-free survival rate were 61.0% and 75.5%, respectively, consistent with other published series over the decade showing a relatively better survival among the young. No significant differences clearly correlated with outcome when comparing non-smokers non-drinkers to ever-smokers and ever drinkers (P>0.05). Overall survival rate and disease free survival rate was found to be significantly higher in patients with early-stage disease than with advanced stage disease (P=0.001, P=0.009 respectively). The strong influence of clinical stage on prognosis emphasizes the importance of early diagnosis and treatment of oral malignancies for this unique clinical subgroup.

Objectives: To assess the efficacy, side effects, and the impact on quality of life with $Qinin^{(R)}$ (Cantharidin sodium) injection combined with chemotherapy for gastric cancer patients. Method: A consecutive cohort of 70 patients were divided into two groups: experimental group with cantharidin sodium injection combined with chemotherapy, while the control group received chemotherapy alone. After more than two courses of treatment, efficacy, quality of life and side effects were evaluated. Results: The response rate of experimental group was not significantly different from that of the control group (P>0.05), but differences were significant in clinical benefit response and KPS score. In addition, gastrointestinal reactions and the incidence of leukopenia were lower than in the control group (P<0.05). Conclusions: $Qinin^{(R)}$ (Cantharidin sodium) injection combined with chemotherapy enhances clinical benefit response, improving quality of life of gastric cancer patients and reducing side effects of chemotherapy. Thus $Qinin^{(R)}$ (Cantharidin sodium) injection deserves to be further investigated in randomized control clinical trails.

Aims: There is a striking sex difference in the incidence of hepatocellular carcinoma (HCC), with a strong predominance for males. However, the impact of sex on the incidence of recurrence after curative resection of HCC remains controversial. Herein, we assess sex differences in the risks of recurrence and mortality for patients undergone curative resection of HCC. Methods: Data from 1,435 HCC patients undergone curative resection (1,228 males and 207 females) between 2004 and 2014 at five institutions in China were retrospectively analyzed. Patients’ baseline characteristics, operative variables, and rates of early recurrence (≤ 2 years after resection), late recurrence (> 2 years) and cancer-specific mortality (CSM) were evaluated and compared. Multivariable competing-risks regression analyses were performed to identify predictors associated with CSM, early and late recurrence. Results: The early recurrence rates between males and females were similar (43.3% vs. 42.0%, P=0.728), but the late recurrence and CSM rates in males were higher when compared to females (17.2% vs. 11.2%, P=0.044; 42.8% vs. 34.3%, P=0.022). Multivariable competing-risks regression analyses revealed no sex difference in early recurrence; however, males had significantly higher late recurrence rate [hazard ratio (HR), 1.752; 95% CI, 1.145-2.682; P=0.010] and CSM rate (HR, 1.307; 95% CI, 1.015-1.683; P=0.038) than females. Conclusions: Males had significantly higher late recurrence and CSM rates after curative resection of HCC than females. This suggests postoperative surveillance for HCC recurrence be varied by sex, especially for patients without recurrence at 2 years after resection.
Suspension Footbridge Form-Finding with Laplacian Smoothing Algorithm
Zhuo-ju Huang,Jie-min Ding,Sheng-yi Xiang 한국강구조학회 2020 International Journal of Steel Structures Vol.20 No.6
In this paper, Laplacian smoothing, which is an algorithm originally used to smooth polygon meshes in computer graphics (CG), is applied to solve a structural form-fi nding problem with the proof that the result of such algorithm is equivalent to force density method. Such CG algorithm is used on the design of a new-built suspension footbridge in Shaoxing, China and the algorithm works well. Since Laplacian smoothing is a pure geometric algorithm without any mechanical concept, the algorithm shows the inner relationship between force and shape, more structural applicable CG algorithms are expected to be found in the future.
