In this paper，a fluorescent probe based on TMS-ethynyl triazolyl benzothiadiazole derivative （BTD）was developed for recognition of copper cation（Cu2+）and fluoride anion（F-）. Sensing behavior of this probe towards anions and cations was monitored by UV-visible and fluorescent spectroscopies in acetonitrile. Among tested anions，only F- induced a decrease in absorption band with a blue shift from 390 nm to 383 nm. Concomitantly，a fluorescence quenching with a blue shift from 496 nm to 488 nm. Among tested cations，Cu2+ led to a decreased absorption band with a red shift and a significant decrease in fluorescent intensity. Interestingly，the fluorescence emission of BTD was highly sensitive to a combination of Cu2+and F- in a sequence dependent manner.

In order to optimize the fidelity and robustness，this paper transforms the digital image watermark into a multi-object problem. Aiming at the problem that the traditional artificial bee colony algorithm is slow convergence speed and easy to fall into local optimal solution，an improved artificial bee colony algorithm is proposed and applied to the digital image watermark processing. The algorithm takes the food source intensity factor and the neighborhood factor into account to update the food source and improve the convergence speed. It uses the DCT to decompose the original image，embeds the watermark into the original image and extracts the watermark blindly. Experimental results show that，the algorithm has a good fidelity and robustness.

Objective To investigate relationships and diagnosis value of urine β2- microglobulin（β2-MG），plasma high sensitive C-reactive protein（hsCRP）and interleukin-6（IL-6）such inflammatory factors in early renal damage of type-2 diabetic patients with hypertension. Methods Urine and plasma samples were collected from 125 type-2 diabetic patients with hypertension and 75 healthy volunteers，and urine β2-MG，hsCRP，IL-6，BUN，SCr，HbAlc of the two groups were tested and compared. Results Urine β2-MG，plasma hsCRP and IL-6 levels of diabetic patients group were higher than those of the healthy group when BUN and SCr were normal range，the difference was statistically significant（ P < 0.05）.There was a positive correlation between urine β2- MG and plasma hsCRP，IL- 6 of diabetic patients. The higher the HbAlc level， the higher the urine β2 - MG， plasma hsCRP and IL- 6. Conclusion A considerable proportion of diabetic patients with hypertension have low renal function while their BUN，SCr are still normal，Urine β2-MG and plasma hsCRP，IL-6 have a good correlationwith early renal damage of diabetic patients with hypertension. It is suggested that combined detection can benefit the diagnosis of early renal damage in such patients，and is in favor of early intervention.
