Objective: To analyze the mortality trend of bladder cancer among residents in Qidong, Jiangsu Province from 1972 to 2016, so as to provide the basis for the prevention and treatment strategy of bladder cancer in Qidong. Methods: The data of bladder cancer was collected from Qidong Cancer Registry.The crude mortality rate ( CR ), age-standardized rate by Chinese population in 2000 (CASR) and world population in 1960 ( WASR ), truncated rate (35-64 years) and cumulative rate ( 0-74 years ) were calculated. The annual percent change ( APC ) was used to analyze the trend of mortality in bladder cancer. Results: During from 1972 to 2016, There were 1 497 deaths due to bladder cancer in Qidong from 1972 to 2016. The CR, CASR and WASR were 2.96/105, 1.83/105 and 1.80/105, respectively. The APCs in CR, CASR, WASR of bladder cancer were 5.29%, 1.86% and 1.81%, respectively ( P<0.05 ), showing upward trends. The truncated rate, cumulative rate and cumulative risk were 1.47/105, 0.17% and 0.17%, respectively. The CR, CASR and WASR in males were 4.71/105, 2.97/105 and 3.31/105, respectively, which was higher than that of 1.26/105, 0.75/105, and 0.66/105 in females ( P<0.05 ). The APC of CR, CASR and WASR in males were 5.71%, 1.96% and 2.17%, respectively ( P<0.05 ), all showed upward trends. For females, the APC of CR was 4.47% ( P<0.05 ), showing an upward trend, but there was no significant change in CASR and WASR ( P>0.05 ). The CR of bladder cancer was high among people aged more than 55 years. The CR in 55-64-year-old group, 65-74-year-old group and more than 75-year-old group showed upward trends, with APC of 4.50%, 2.22% and 4.51%, respectively ( P<0.05 ). Conclusions From 1972 to 2016, the mortality of bladder cancer in Qidong showed an upward trend, which was relatively high in men and people aged over 55 years.

To ascertain current situation of wild Marsdenia tenacissima resources in Honghe, Yunnan province, the distribution, habitat characteristic and resources reserves of M. tenacissima were surveyed based on interviews and investigation. The results showed that M. tenacissima was found in 7 counties such as Jinping, Mengzi etc, and distributed mainly on the mountainsides from 800 m to 1 200 m. And distribution was affected by many factors, such as light, heat, topography, soil, and vegetation. M. tenacissima grew well in distribution areas. M. tenacissima had averagely a weight of 2.8 kg per plant.

OBJECTIVETo explore the effect of Ang-2 on angiogenesis in gastric cancer.

METHODSThe expression of Ang-2 mRNA was analyzed by RT-PCR and the expression of VEGF and CD34 was detected by immunohistochemistry in 36 cases of gastric cancer tissues and their paired adjacent gastric mucosa.

RESULTSThe expression of Ang-2 mRNA was found both in gastric cancer and their paired adjacent gastric mucosa; the correlationship between the general expression levels of Ang-2 mRNA and microvessel density (MVD) in gastric cancer tissues was not found. However, in 27 cases whose Ang-2 mRNA expression levels in cancer tissues were lower than those in adjacent gastric mucosa. A significant positive correlation between the expression level of Ang-2 mRNA and MVD in the tumor tissues was found (r = 0.411, P < 0.05). In these 27 cases, the MVD in the gastric cancer tissues with positive VEGF expression (45.45 +/- 10.30) was higher than that with negative VEGF expression (30.15 +/- 8.69, P < 0.05), whereas in the other 9 cases whose expression levels of Ang-2 mRNA in cancer tissues were higher than those in adjacent gastric mucosa, a significant negative correlation between expression level of Ang-2 mRNA and MVD in the tumor tissues (r = -0.758, P < 0.05), but without correlation between the MVD and VEGF.

CONCLUSIONUnder the conditions that the expression of Ang-2 mRNA in cancer tissues was lower than that in adjacent gastric mucosa, VEGF could promote the sprouting of new vessels along with Ang-2 upregulation. But under the conditions that the expression of Ang-2 mRNA in cancer tissues was higher than that in adjacent gastric mucosa, Ang-2 inhibited angiogenesis. Angiopoietin-2 may play a dual effect on angiogenesis in gastric cancer.

Objective To quantitatively analyze and compare the texture features of thermal and chemical lesions on the porcine striated muscle, in vitro extracted from high-frequency ultrasonograms using computer-assisted image analysis technique, and to investigate the application values. Methods The thermal lesion and chemical lesion were induced in vitro in porcine striated muscle by microwave ablation and anhydrous acetic acid injection, respectively. The two dimension (2D) ultrasonographic ifndings were qualitatively compared between the groups of thermal and chemical lesion models, in which eight textural features in geometric mathematics extracted from 2D ultrasonograms were quantitatively analyzed by a technique of computer-assisted image analysis named multiscale decomposition method of echo intensity of interface relfections. Results As expected, microwave ablation and anhydrous acetic acid caused signiifcant changes of several texture features extracted from ultrasonograms. There were significant differences between the normal group and microwave ablation group in grayscale mean (Mean), irregularity (IRGL) and periodicity of distribution (POD) as follows (Mean: 1.9143±0.2914 vs 1.2334±0.3357, t=-5.306, P=0.000; IRGL: 0.5577±0.0334 vs 0.5092±0.0459, t=-2.957, P=0.007; POD: 0.000 27±0.000 005 vs 0.000 29±0.000 008, t=4.782, P=0.000). There were signiifcant differences between the normal group and anhydrous acetic acid injection group in number of blobs (NOB), size of blobs (SOB) and periodicity of distribution (POD) as follows (NOB: 51.0324±13.6998 vs 31.6042±4.8315, t=4.633, P=0.000; SOB:16.4843±3.9349 vs 25.6230±2.3555, t=6.903, P=0.000;POD:0.000 26±0.000 015 vs 0.000 29±0.000 008, t=-4.459, P=0.000). For each group of injured regions, there were significant differences between the microwave ablation group and anhydrous acetic acid injection group in Mean, IRGL, NOB and SOB as follows (Mean: 1.2664±0.2688 vs 1.9143±0.2914, t=-5.661, P=0.000; IRGL: 0.5220±0.0422 vs 0.5577±0.0334, t=-2.295, P=0.032;NOB:51.0324±13.6998 vs 34.5856±2.6362, t=4.048, P=0.000;SOB:16.4843±3.9349 vs 25.3176±2.3501, t=-6.676, P=0.000). Conclusion Technique of computer-assisted image analysis named multiscale decomposition method of echo intensity of interface relfections, based on multiscale blob features extraction, was useful to differentiate ultrasonic texture features between the groups injured in our study, which established quantitative muscle ultrasound as a practical and reliable tool for the muscle injury diagnosis to distinguish the structural changes induced by different physiochemical factors.
